get_class · Class / Object · PHP

Returns the name of the class of an object

Syntax

get_class ( [ object $object ] ) : string

Parameters

object

The tested object. This parameter may be omitted when inside a class.

Note: Explicitly passing NULL as the object is no longer allowed as of PHP 7.2.0. The parameter is still optional and calling get_class() without a parameter from inside a class will work, but passing NULL now emits an E_WARNING notice.

Return

Returns the name of the class of which object is an instance. Returns FALSE if object is not an object.

If object is omitted when inside a class, the name of that class is returned.

If the object is an instance of a class which exists in a namespace, the qualified namespaced name of that class is returned.
