Description

string get_parent_class ([ mixed $object ] )

Retrieves the parent class name for object or class.

Parameters

object: The tested object or class name

If called without parameter outside object, this function returns FALSE.

ChangeLog

Version Description

Before 5.1.0 If called without parameter outside object, this function would have returned NULL with a warning.

Since 5.0.0 The object parameter is optional if called from the object's method.

Since 4.0.5 If object is a string, returns the name of the parent class of the class with that name.

Examples

Example #1 Using get_parent_class()


<?php



class dad {

    function dad()

    {

    // implements some logic

    }

}



class child extends dad {

    function child()

    {

        echo "I'm " , get_parent_class($this) , "'s son\n";

    }

}



class child2 extends dad {

    function child2()

    {

        echo "I'm " , get_parent_class('child2') , "'s son too\n";

    }

}



$foo = new child();
