            var_dump ( $ error );
        }
    }
}
 
class test{
    function test_shutdown()
    {
        // register a shutdown function will be executed when the suspension php 
        register_shutdown_function ([ new new errors (), 'shutdown' ]);
         // call the function test here that does not exist 
        testaa ();
    }
