(PHP 5)

class_parents --  Return the parent classes of the given class

Description

This function returns an array with the name of the parent classes of the given class.

Parameters

class

An object (class instance) or a string (class name).

autoload

Whether to allow this function to load the class automatically through the __autoload magic method. Defaults to TRUE.

Return Values

ChangeLog

VersionDescription
5.1.0 Added the option to pass the class parameter as a string. Added the autoload parameter.

Examples

Example 1. class_parents() example

<?php

class foo { }
class bar extends foo {}

print_r(class_parents(new bar));

// since PHP 5.1.0 you may also specify the parameter as a string
print_r(class_parents('bar'));


function __autoload($class_name) {
   require_once $class_name . '.php';
}

// use __autoload to load the 'not_loaded' class
print_r(class_parents('not_loaded', true));
?>

The above example will output something similar to:

Array
(
    [foo] => foo
)

Array
(
    [parent_of_not_loaded] => parent_of_not_loaded
)
