(PHP 5, PHP 7, PHP 8)
class_parents — Return the parent classes of the given class
$object_or_class
, bool $autoload
= true
): array|false
This function returns an array with the name of the parent classes of
the given object_or_class
.
object_or_class
An object (class instance) or a string (class name).
autoload
Whether to autoload if not already loaded.
An array on success, or false
when the given class doesn't exist.
Example #1 class_parents() example
<?phpclass foo { }class bar extends foo {}print_r(class_parents(new bar));// you may also specify the parameter as a stringprint_r(class_parents('bar'));spl_autoload_register();// use autoloading to load the 'not_loaded' classprint_r(class_parents('not_loaded', true));?>
The above example will output something similar to:
Array ( [foo] => foo ) Array ( [foo] => foo ) Array ( [parent_of_not_loaded] => parent_of_not_loaded )
Note: To check that an object extends a class,
instanceof
or the is_a() function should be used instead.
