get_class
Gets the name of the class of the given object.
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 and emits an E_WARNING. As of PHP 8.0.0, a TypeError is emitted when null is used.
Return Values
Returns the name of the class of which object is an instance.
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.
Exceptions and Errors
If get_class is called with anything other than an object, TypeError is raised. Prior to PHP 8.0.0, an E_WARNING level error was raised.
If get_class is called with no arguments from outside a class, Error is raised. Prior to PHP 8.0.0, an E_WARNING level error was raised.
Changelog
| Version | Description |
| 8.0.0 | Calling this function from outside a class, without any arguments, will trigger an Error. Previously, an E_WARNING was raised and the function returned false. |
| 7.2.0 | Prior to this version the default value for object was null and it had the same effect as not passing any value. Now null has been removed as the default value for object, and is no longer a valid input. |
