Return the traits used by the given class
array class_uses ( mixed $class [, bool $autoload = true ] )
This function returns an array with the names of the traits that the given class
uses. This does however not include any traits used by a parent class.
Parameters:

An object (class instance) or a string (class name).
autoload
Whether to allow this function to load the class automatically through the __autoload() magic method.
Returns:
An array on success, or FALSE
on error.
Examples:
class_uses() example
<?php trait foo { } class bar { use foo; } print_r(class_uses(new bar)); print_r(class_uses('bar')); function __autoload($class_name) { require_once $class_name . '.php'; } // use __autoload to load the 'not_loaded' class print_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 )
