Accourding to the 'Changes to variable handling' (http://php.net/manual/en/migration70.incompatible.php#migration70.incompatible.variable-handling.indirect), arrays that i want to pass as function name i have to write as ($foo->$bar)['baz']()

In my case i have an api that check the url wich class and function needed to be loaded for example (in short):
url: users/getData

i split the url with explode on '/' and then pass the second url key [1] as a function:
$url = 'users/getData';
$urlSplit = explode('/', $url, 2);
($class->$urlSplit)[1]($param1, $params2);

It's weird to write it like this but this ain’t working.

I need to save the function to a new variable to fix it like this:
$function = $urlSplit[1];
$class->$function($param1, $params2);
