EXAMPLES
       Example #1

	      class_implements(3) example

	      <?php

	      interface foo { }
	      class bar implements foo {}

	      print_r(class_implements(new bar));

	      // since PHP 5.1.0 you may also specify the parameter as a string
	      print_r(class_implements('bar'));

	      function __autoload($class_name) {
		 require_once $class_name . '.php';
	      }

	      // use __autoload to load the 'not_loaded' class
	      print_r(class_implements('not_loaded', true));

	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [foo] => foo
	      )

	      Array
	      (
		  [interface_of_not_loaded] => interface_of_not_loaded
	      )
