Description

get_parent_class(object|string $object_or_class = ?): string|false

Retrieves the parent class name for object or class.

Parameters

object_or_class

The tested object or class name.

Changelog

VersionDescription
8.3.0Calling get_parent_class() without an argument now emits an E_DEPRECATED warning; previously, calling this function inside a class returned the name of that class.
8.0.0The object_or_class parameter now only accepts objects or valid class names.

Examples

Example #1 Using get_parent_class()

<?php

class Dad {
function __construct()
{
// implements some logic
}
}

class Child extends Dad {
function __construct()
{
echo "I'm " , get_parent_class($this) , "'s son\n";
}
}

class Child2 extends Dad {
function __construct()
{
echo "I'm " , get_parent_class('child2') , "'s son too\n";
}
}

$foo = new child();
$bar = new child2();

?>

The above example will output:

I'm Dad's son
I'm Dad's son too
