class_uses - Return the traits used by the given class

SYNOPSIS
       array class_uses (mixed	$class, [bool  $autoload = true])

       parent class.

PARAMETERS
	      o $class
		- An object (class instance) or a string (class name).

EXAMPLES
       Example #1

	      class_uses(3) 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
	      )
