PHP supports Object Orientation since the release of PHP3. Further Improvements were made by PHP 4. Since the introduction of the PHP 5 lots of the features of the Object Orientation were included. You could create a class in PHP as the following :

class <<class name>> {

<<private/public/ $property name>> // properties list

….

//method list

function <<function name>> {

}

….

}

It is same as the other Object Oriented programming. Try it out. If you have any problems leave a comment.

You can create classes and sub classes in PHP 5. Example is given here.

****Implementing Parent Class

class parentClass{

private $parentName;  //properties can be public, private or protected.

private $parentProperty;

private function1{ //methods also can be public, private or protected.

//statements

}

function2{

//statements

}

}

****** Implementing sub class

class childClass extends parentClass{

private $childName;

private $childProperty;

function1{

//statements

}

function2{

//statements

}

}

For more details you can refer to http://php.net/manual/en/language.oop5.php

Yes it is possible. You can create a separate file for the classes you created and call using following code.

using keyword "require"

require( "class/class_db.php" );

or using keyword "include"

include("class/class_item.php");

*** It is better including each class in a separate file. By that way it is easy to modify the code.

Once you have linked the classes objects could be created using the key word "new"

$obj_item = new class_item();

For further details on creating classes and objects refer to official php site php.net/manual/en/language.oop5.php.

It is possible of linking the classes using the key word "include". And then work as the tutorial to create instances and use the object oriented features.
