PHP can be very useful in your webiste design, I use PHP for my websites difficult functions such as forums, blogs, chat, user forms, and shopping cart interface. But did you know you can use simple PHP for your website navigation systems?

The use of PHP for your websites header, left side navigation, and bottom of page information can be a great asset. Now I know what you are thinking, PHP can be complicated and intimidating to many of you, but first let me explain. Using simple PHP include commands is a method any webmaster at any expertise level from novice to expert can implement with ease.

Most find editing PHP a frightening endeavor, but never fear, I will show you how.

A lot of us still use tables when designing our web pages instead of CCS, below is a veiw of the basic setup I will be discussing in this article:

Go here to see Image http://www.newcybertech.com/images/Artica1.jpg

As you can see from the image above, all the content surrounding the main content of each page will be shown in PHP and this is what this article is all about. The benefit of this technique will be when you update any of the surrounding PHP files, the results will be reflected on every page on your website that you have setup in this fashion. This sounds great right, but hold on, there is one more benefit.

You may say the same thing can be accomplished with robot include commands, but there is a catch to that.

The problem with the robot include command is that this content can not be seen by search engine robots. We all know that content is king to achieving high search engine rankings, so why hide the content you have? That’s why what I am about to teach you and using PHP for your website navigation is so important.

“All the information and links included in your navigation PHP can be seen and indexed by all the search engine robots for higher rankings.”

Now on to how it all Works:

Please read below if you need this information, if not browse down to the steps to generate PHP navigation on your website.

PHP: Hypertext Preprocessor, better known as PHP, is a highly popular, server-side scripting language that can be embedded directly into HTML coding.PHP can do anything that CGI can do, such as process form data and auto generate dynamic content, but PHP can do much more.It can be used on all major operating systems and supports most web servers.PHP is used by inserting PHP code inside your web page’s HTML code. When the page is called, your server automatically executes the code. What’s more, your visitors don’t need any special plug-ins for the code to run, as it will be displayed just like your HTML coding.As PHP is a server-side scripting language, although your visitors will not need to install any new software, PHP must be set up on your server.

Following is a very simple script that will test your server to ensure PHP is installed. It is a standard PHP function called phpinfo, which instructs the browser to print out information in regard to the set up of your server.

To use the script, simply copy the following three lines of code and paste them into a plain text editor, such as Note Pad.

Save the file as phpinfo.php and upload it to your server where you store your HTML files.

To run the script, simply point your browser to the script address. It should look something like this:

http://www.yourdomain.com/phpinfo.php

If PHP is installed on your server, you will be presented with a page of information about the PHP installed on your server.

If PHP isn’t installed, you will be prompted to download the file. In this case, you’ll need to contact your web host and ask them to install it, as it is free to download and install.

You can learn more about PHP and download it at

http://www.php.net/.

Steps to generate PHP navigation on your website.

First of all you need to enable create a php file with html includes using the php include function. This is easily done by adding one line to your .htaccess file for your apache driven site and have php parsed in html files. To do this logon to your websites FTP account, go into the .htdocs file, find the .htaccess file, edit it to add this one line of code to the file:

AddType application/x-httpd-php .php .html

With that, you can have php blocks parsed in your html files so long as you put the php code in php tags. Example below:

php Code:

We will get into how to use the above command a little later in this article . Now on to the steps:

Step 1. Build the the following pages in your favorite HTML editor: A. header.html B. left.html C. bottom.html D. right.html (optional) Or you can name these files what ever you like, but I will be referencing them as the above for this article. Once you have these pages built to your liking, we now start implementing with PHP. First build a new Index.html page, you can name it TEST or something until you get it the way you want it. Set it up with tables to look like the page below:

Go here to see Image http://www.newcybertech.com/images/Artica2.jpg

Step 2. Now here is the trick, rename each HTML page you just built, “header.html, left.html, bottom.html, and right.html (optional)” to the .php file extension. You can do this by opening each .html file in a text file editor such as Notepad and save as .php to the same directory as the .html files on your server. You will now have a copy of each file in HTML and PHP format.

Step 3. We are now ready to use the new PHP files, in each table around your main content we will insert the Command functions. See example below:

Go here to see Image http://www.newcybertech.com/images/php.jpg

Step 4. Open your new index page in your favorite browser and you will now see all the HTML pages you built come together as one page by using PHP.

Go here to see Image http://www.newcybertech.com/images/newcybertech.jpg

Step 5. Editing the new PHP navigation pages is easy, all you need to do is edit the HTML file you built in you favorite HTML editor. When your are done just copy the pages HTML and then paste it into the corresponding PHP file. To do this open the PHP file with a text editor and replace the HTML with in it with the edited version of HTML and save it as .php again. Now your PHP file is updated to match your edited HTML file.

In conclusion: Now when ever you update your website header and navigation pages the results will be reflected on every page on your website that you have setup in this fashion. And as a added bonus all the information and links included in your navigation PHP can be seen and indexed by all the search engine robots for higher rankings.

Java is a programming technology developed by Sun Microsystems. Java is an object-oriented language. Java can be used for web development.

Java is platform independent. The java code is compiled into a bytecode that can be run on a Java Virtual Machine(JVM). So Java code will run on any system that has a JVM installed in it. Java is robust, flexible and scalable. It can also be used to communicate with legacy systems.

Java provides a lot of classes or objects. Java Swings is a tool-kit that has a wide range of objects from text-boxes to menu bars to make website design easy.

Java programs consist of classes. Classes consist of methods. Java language can be used to develop object oriented applications.

The simplest form of a java program is as follows:

// Java program 1

public class Welcome1{

public static void main (String args[])

{

System.out.println ( “Welcom”);

}

}

In the above example;

// denotes that the statement is a comment and it not considered for programming.

The statement public class welcome1 is used to define the class. Java programs consist of classes defined like this.

The statement public static void main is used to define program building block. Every java program consist of a main function.

The statement System,out.println is used to produce the output. It gives instructions to the computer to print the String as an output.

Save the above program as Welcome1.java in the java Bin Directory.

Example C:javabin

The next step is to create the .class file by compiling the .java file.

In the dos prompt,

Type javac Welcome1.java and press enter.

It will produce a .class filee.

The final step is to run the class file. Type java Welcome1 to execute the .class file.

You will receive the desired output.

deep raj asked:


Before we start any discussion about Persistence technologies, we need to understand what exactly Persistence is in computer science. Persistence, in simple terms is the ability to retain data structures between various program executions. A perfect example of this would be a word processor saving undo history. In practice, this is achieved by storing the data in non- volatile storage such as a file system or a relational database or an object database.

The popularity of databases has increased manifold in the past few years. Java has become the preferred choice of developers for developing secure, flexible, and scalable database driven web applications. These web applications require objects to be associated with appropriate databases. Hibernate, along with other persistence technologies associate’s objects with the appropriate database in a simple, straight forward and natural way.

Hibernate is one such effort from the Java community to develop many object oriented solutions to data persistence. Any kind of Java persistence solution includes two main elements i.e. ORM (Object Relational Mapping) and OOM (Object Oriented Modeling).

Hibernate has become immensely popular amongst the developer community as it is a free, powerful, high performance open source object - relational mapping persistence Java package that makes it easier to work with relational databases for Java Applications.

Apart from Hibernate, other popular open source Java persistence technologies include JDBC, abates, JDO, Top Link and CMP Entity Beans. These technologies provide a standardized object-relational mapping mechanism.

Java persistence application programming Interface or JAVA Persistence API is the latest version of the Java Data Objects (JDO) technology which was the earlier persistent technology used by developers. JPA or the Java Persistence API is the latest Java Specification standard for java enterprise applications. The Java Persistence API is a java programming language framework that allows developers to manage relational data in Java standard edition and Enterprise Edition applications. Java Persistence API originated as part of the work of the JSR 220 expert group.

The java persistence API’s has been developed after drawing upon the best ideas from other prevalent persistence technologies like Top link, JDO, Hibernate etc. In simple words, Java Persistence API is a Plain Old Java Object API for object /relational mapping and supports a rich, SQL –like query language for both static and dynamic queries.

Vendors involved in application development have found that the use of Hibernate technology with Java persistence API’s helps build flexible, database driven web applications that are highly scalable and involve complex business processes.

The Java Persistence API is the standard object/relational mapping and persistence management interface of the Java EE 5.0 platform and Java Web Services Development . As part of the EJB 3.0 specification effort, it is supported by all major vendors of the Java industry for improving Java Web Development in India and Globe.

Introduction

At the time of development, sometimes it is necessary to store the state of the object in the file system. Some objects may or may not be stored in the file system depending upon the structural intensity of the object graph. In this article, I will focus on two major aspects of the object persistence. Before going to this subject, I would like to tell you about the significance of the object persistence. Object persistence presupposes the state of the object in the file system. In this matter you can make argument regarding object persistence in the database, which hibernate does. But so far this article is concerned I will give glimpse on persistence in the file system for all convenience. The state of object signifies the attributes or properties of the object in the broader sense. The object graph represents the internal morphological structure of the object. So persisting object means, you are going to store all the internal changed structure of the object.

Technicalities

There are several ways you can persist the state of the object. You can take help from Java IO system to store the object in the file system. However there are convenient approaches you can meet your expectations in this regard. One way is the textual representation of the object graph in the file system and another way is the binary representation of the object graph. These ways are very much convenient and easy from the view point of development. You can achieve the textual representation of the object graph using XMLEncoder and you can achieve the binary representation of the object graph using java object serialization process. Let me explain the two approaches below.

Persistence using XMLEncoder

XMLEncoder class is an approach to persist the object graph in an XML document or simply in an XML file. It provides the flexibility of storing the object as a textual approach. In this approach you can see the XML file and you can easily understand the attributes of the object. Similarly to obtain the object graph from the XML file, you can use XMLDecoder. All these classes have been defined in the java.beans package. Let me clarify all the aspects by citing the complete example.

Create a normal java bean or class having the following structure.

Let us see the class called Emp.java which is a normal java bean.

There is another test harness class called TestPersistence.java which exposes the use of XMLEncoder and XMLDecoder.

The following is the Emp.java.



package com.core.persist;

/**

* This is a simple java bean.

* @author Debadatta Mishra(PIKU)

*

*/

public class Emp

{

private String name = null;

private int age = 0;

private String empId = null;

public Emp()

{

super();

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public String getEmpId() {

return empId;

}

public void setEmpId(String empId) {

this.empId = empId;

}

}



The following is the TestPersistence.java



package com.core.persist;

import java.beans.XMLDecoder;

import java.beans.XMLEncoder;

import java.io.BufferedInputStream;

import java.io.BufferedOutputStream;

import java.io.FileInputStream;

import java.io.FileOutputStream;

/**

* This is a test harness class to display the

* use of XMLEncoder and XMLDecoder.

* @author Debadatta Mishra(PIKU)

*

*/

public class TestPersistence

{

public static void main(String[] args)

{

Emp emp = new Emp();

emp.setName(”John”);

emp.setAge(23);

emp.setEmpId(”A123″);

try

{

/*

* The following codes are used to persist the Emp object graph

*/

XMLEncoder encoder = new XMLEncoder(new BufferedOutputStream(

new FileOutputStream(”C:/emp.xml”)));

encoder.writeObject(emp);

encoder.flush();

encoder.close();

/*

* The following codes are used to obtain the Emp object graph

* from the XML document

*/

XMLDecoder decoder = new XMLDecoder(new BufferedInputStream(

new FileInputStream(”C:/emp.xml”)));

Emp emp1 = ( Emp )decoder.readObject();

decoder.close();

System.out.println(”Emp Name=>”+emp1.getName());

System.out.println(”Emp Age=>”+emp1.getAge());

System.out.println(”Emp Id=>”+emp1.getEmpId());

}

catch( Exception e )

{

e.printStackTrace();

}

}

}



The following is the output of the above example.

If you run the above classes, an XML document called emp.xml will be created in the specified location. The xml document will look like the following.

23

A123

John

So you have stored the state of the Emp object in the xml document. It is also required to load the Emp object from the xml document. For this purpose you have use XMLDecoder which has been used in the test harness class. If you want to test the above two classes, you can copy the classes and change the package structure and you can run it. In case of loading the object using XMLDecoder, it takes help from java’s reflection system.

Advantages of XMLEncoder and XMLDecoder

• Since it is a textual representation of the object graph, anybody can see the XML file and it helps in the portability to any other system.

• If you want to change the value of a particular property of an object, you can do it directly in the XML document so that while using XMLDecoder, you will get your modified value.

• If the object’s variables are declared transient, still you are able to store the complete object graph along with the transient variable’s value. This case is not possible in case of java object serialization.

• It is also very easy and convenient in case of object inheritance. There is no need to bother about the super class and sub class. Some of the limitations of normal java object serialization can be over come in this approach.

Persistence using Serialization

Serialization is a java’s default mechanism to save the state of the object or simply the object graph in the file system. In this case your object will be persisted in the file system where the file is not human readable. It means that you are going to store the binary representation of the object graph in the file system. This object serialization can be achieved using the writeObject() method of the class ObjectOutputStream. The main thing you have to remember is that the object you are going to persist must implement Serialization interface which is called as marker interface. In next article I will explain you the use and the beauty of the marker interfaces. Similarly deserialization means retrieval of object from the saved state. You can achieve the deserialization using readObject() method of the ObjectInputStream class.

Please refer below the following piece of code to achive serialization.

The following is class called Emp. It implements Serializable interface. There is another class called TestSerialization. This class performs both serilization and deserilization. This is the normal way of serilization concept from java.



package com.core.persist;

import java.io.Serializable;

/**

* This is a simple java bean.

* @author Debadatta Mishra(PIKU)

*

*/

public class Emp implements Serializable

{

private static final long serialVersionUID = -164971138528601769L;

private String name = null;

private int age = 0;



public Emp()

{

super();

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

}

Class TestSerialization.java



package com.core.persist;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.ObjectInputStream;

import java.io.ObjectOutputStream;

public class TestSerialization

{

public static void main(String[] args)

{

Emp emp = new Emp();

emp.setAge(23);

emp.setName(”John”);



try

{

/*

* Code to serialize or persist the object

*/

ObjectOutputStream ous = new ObjectOutputStream( new FileOutputStream(”D:/test.ser”));

ous.writeObject(emp);

ous.close();

/*

* Code to deserialize the object

*/

ObjectInputStream oin = new ObjectInputStream( new FileInputStream(”D:/test.ser”));

Emp emp1 = ( Emp )oin.readObject();



System.out.println(”Emp age—-”+emp1.getAge());

System.out.println(”Emp Name—-”+emp1.getName());



}

catch( Exception e )

{

e.printStackTrace();

}

}

}



You can run the above code in your editor to test the functionalities relating to serialization.

Now I put forward some cases for seriliazation.

Case-1:

If your object does not implement Serializable interface,

In order to serialize an object, it is a must that the class must implement seriliazable interface. This is the required principle of serilization. Oterwise it will throw NotSerializationException.

There is another way, if your class does not implement Serilizable interface, you have to declare the object as transient. So that that object state will not be persisted.

Case-2:

In case of inheritance, your super class does not implement Serializable interface and sub class also does not.

In this case serilization will not happen . If you are interested to store the all the properties of the object you can go for XMLEncoder and XMLDecoder as I have alredy explained you.

Case-3:

In case of inheritance, your class implements Serializable interface and sub class does not.

In this case, you should not worry about it, seriliazation happens.

Case-4:

In case of inheritance, your super class does not implement Serializable interface but your sub class does.

Seriliazation will happen but with a lemon falvour. Here no exception will be thrown but your super class data members or object properties of your super class will be not be persisted. When you deserialize object, you will get the default values of your super class object.

Case-5:

This is the best case. You super class and sub class implement serializable interface.

Everything is fine here, serilization happens.

Case-6:

If your object uses transient modifiers inside the objects,

You have to remember that transient objects or variables will not be persisted in case of serialization.

Case-7:

If your object uses volatile modifiers inside the object,

There is nothing to worry about, serialization will happen normally and data will be persisted.

Case-8:

If your object uses static modifiers inside the object,

You have to remember that,since static is not a part of object, so static variables or static object reference will not be persisted in case of seriaization.

Case-9:

It is a very special case I am going to focus on. You may encounter the following situations at the time of serialization.

• You are not sure whether your super class does implement serializable interface.

• You do not have access to the source code of your super class.

• Your super class may be a final class.

• Your super class may contain noe-serializable object reference.

In this case, if you feel frustration and disappointment, you can go for XMLEncoder and XMLDecoder as I have already explained.

If you want to persist the object using java’s serialization concept and mechanism, you have to do it little bit intelligently and manually.

Please refer to the following piece of code.

The following class name is Emp.java

proj.setProjectId(oin.readInt());

proj.setPojectName( (String) oin.readObject() );

}

catch( Exception e )

{

e.printStackTrace();

}

}



}



The following class name is Project.java



package com.core.persist;

/**

* @author Debadatta Mishra(PIKU)

public class Project

{

private int projectId = 0;

private String pojectName = null;

public Project()

{

this.pojectName = pojectName;

}

public int getProjectId() {

return projectId;

}

public void setProjectId(int projectId) {

this.projectId = projectId;

}



}



The following class name is TestSerialization.java which is test harness class.



package com.core.persist;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.ObjectInputStream;

import java.io.ObjectOutputStream;

/**

* @author Debadatta Mishra(PIKU)

public class TestSerialization

{

public static void main(String[] args)

{

Emp emp = new Emp();

emp.setAge(23);

emp.setEmpId(”A1″);

emp.setName(”John”);

Project proj = new Project();

proj.setProjectId(5555);

proj.setPojectName(”XYZ”);

emp.setProj(proj);



try

{

ObjectOutputStream ous = new ObjectOutputStream(

new FileOutputStream(”D:/test.ser”));

ous.writeObject(emp);

ous.close();



ObjectInputStream oin = new ObjectInputStream(new FileInputStream(

“D:/test.ser”));

Emp emp1 = ( Emp )oin.readObject();



System.out.println(”Emp age—-”+emp1.getAge());

Project proj1 = emp1.getProj();

System.out.println(”Proj Id—–”+proj1.getProjectId());

System.out.println(”Proj Name—-”+proj1.getPojectName());

}

catch( Exception e )

{

e.printStackTrace();

}

}

}



Please see the two methods writeObject() and readObject() inside the class Emp. These two methods are significant in the sense that you are going to achieve serialization with your default object as well as manual serialization with the non serializable object with some data. When you call the methods writeObject() and readObject() for a particular object these methods will be invoked automatically and will persist some default data. In these particular methods you are persisting data manually and thereby making the whole object serializable.

Hibernate, along with other persistence technologies associate’s objects with the appropriate database in a simple, straight forward and natural way.

 

Hibernate is one such effort from the Java community to develop many object oriented solutions to data persistence. Any kind of Java persistence solution includes two main elements i.e. ORM (Object Relational Mapping) and OOM (Object Oriented Modeling).

 

Hibernate has become immensely popular amongst the developer community as it is a free, powerful, high performance open source object - relational mapping persistence Java package that makes it easier to work with relational databases for Java Applications.

 

Apart from Hibernate, other popular open source Java persistence technologies include JDBC, abates, JDO, Top Link and CMP Entity Beans. These technologies provide a standardized object-relational mapping mechanism.

 

Java persistence application programming Interface or JAVA Persistence API is the latest version of the Java Data Objects (JDO) technology which was the earlier persistent technology used by developers. JPA or the Java Persistence API is the latest Java Specification standard for java enterprise applications. The Java Persistence API is a java programming language framework that allows developers to manage relational data in Java standard edition and Enterprise Edition applications. Java Persistence API originated as part of the work of the JSR 220 expert group.

 

 

The java persistence API’s has been developed after drawing upon the best ideas from other prevalent persistence technologies like Top link, JDO, Hibernate etc. In simple words, Java Persistence API is a Plain Old Java Object API for object /relational mapping and supports a rich, SQL –like query language for both static and dynamic queries.Vendors involved in application development have found that the use of Hibernate technology with Java persistence API’s helps build flexible, database driven web applications that are highly scalable and involve complex business processes.

 

 

 

The Java Persistence API is the standard object/relational mapping and persistence management interface of the Java EE 5.0 platform and Java Web Services Development . As part of the EJB 3.0 specification effort, it is supported by all major vendors of the Java industry for improving Java Web Development in India and Globe.

PHP is an open sourced server side scripting language and almost used in foremost operating systems like Linux, UNIX and also in Windows. PHP follows object oriented programming (OOPs), practical programming rules and nearly a combination of them. It uses command line interface, desktop applications thus it is know as the best traditional server side scripting language.

PHP programming supports most of the reputed database connections like Oracle, SQL, My SQL, and ODBC thus it is an easy choice for freelance programmers to build their dynamic pages with the help of PHP development. The latest version is also popular because it can be embedded HTML coding directly and can be carried by nearly all of the web servers.

PHP is a popular language because of its numerous features infused specifically to design websites or you can say to develop dynamic pages. PHP engine and the PHP coding can be used in every platform that increases flexibility of PHP language. Basically PHP is profitable for both programmers and designers, programmers who realizing its flexibility and tempo and web designers who worth its handiness and user-friendliness.

PHP language can develop giant business services like CRM solutions, community sites, chatting forums and E-Commerce shopping cart as well. Several pools of qualified web programmers are using PHP development for organizing their goal, resource planning and fulfilling their client requirements.

Here are some few things which you can perform with PHP:

• Design HTML web forms.

• Superb Database usability to store records.

• Calculate visitors by sessions and cookies.

• You can use arrays as well.

• Play with files through file management system.

• Creating XML for large number of product list on E-Commerce

Serialization

Serialization is not needed for all kind of databases. In some particular databases like ODBC, MS SQL etc when you wish to pass a value without mentioning its type, it gets dumb. This problem is solved properly in the latest version of PHP. This is also an added advantage of PHP over all king of scripting languages.

Using PHP to Improve Design your website

PHP has many capabilities features designed specifically for use in Web sites, including the following:

1. Securing Your Website: PHP is designed to allow user level access to the file system, it’s entirely possible to write a PHP script that will allow you to read system files such as password, modify your Ethernet connections, etc. thus this can provide a customer with an exclusive membership in the business.

2. Working with Web Forms: HTML form can be displayed by PHP and it is the best way to know more about the requirements of your customers and to gather note about their detailed benefits.

3. Communicate with Your Databases: When a persistent connection is requested, PHP checks if there’s already an identical persistent connection and if it exists, it uses it. If it does not exist, it creates the link.

4. Customer Loyalty Functions: PHP allows content and applications to be generated and run server-side. This is highly advantageous to web users as they do not have to rely on their own system resources to generate or run content on their own systems. This allows for faster delivery of applications to the user and reduces errors and problems due to browser incompatibilities.
