Object:

 

An object is anything that has state and behavior. An object is an instance of a class.

 

Example:

 

Dog

 

State: name, color, breed

 

Behavior: sitting, barking, waging tail, running

 

 

Objects in PHP:

 

 The concept of objects in php is same as in other programming languages. Objects in php are created with new keyword to instantiate a class.

 

Code:

 

 

<?php

class foo

{

    function do_foo()

    {

        echo "Doing foo.";

    }

}

$bar = new foo;       //create object of class foo

$bar->do_foo();

?>

 

 

Delete Objects in PHP:

 

To delete an object in php we use unset () function that take object as a parameter and delete that object. The unset () function is built in function in php.

 

 

Code:

 

 

 

 

<?php

function destroy_foo()

{

    global $foo;

    unset($foo);

}

 

$foo = 'bar';

destroy_foo();

echo $foo;

?>
