class_uses — Return the traits used by the given class
This function returns an array with the names of the traits that the
given object_or_class
uses. This does however not include
any traits used by a parent 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_uses() example
<?phptrait foo { }class bar { use foo;}print_r(class_uses(new bar));print_r(class_uses('bar'));spl_autoload_register();// use autoloading to load the 'not_loaded' classprint_r(class_uses('not_loaded', true));?>
The above example will output something similar to:
Array ( [foo] => foo ) Array ( [foo] => foo ) Array ( [trait_of_not_loaded] => trait_of_not_loaded )
