PHP 5.3: pass by reference problems

Interesting problem in the new PHP 5.3 (I'm currently using 5.3.2-1ubuntu4.2).

Imagine you have following code:
-> Function test() takes 2 arguments. The 2 arguments are referenced arguments (notice the '&'):

function test(&$arg, &$arg2){
  // some code
}

... and you want to call it using the call_user_func_array() function.
In PHP 5.2 (or lower), you could simply do this by:

call_user_func_array('test', $arg1, $arg2);

... but since PHP 5.3, this will not work any longer :-). You cannot pass arguments by reference to functions called with callbacks. The reason is that call_user_func_array() parameters are not references. If you really need to do it with a callback, you will need to wrap the parameters into an object (objects are always passed by reference)

function test($params){
  // some code
  echo $params->arg1;
  echo $params->arg2;
}
...
$params = (object) array('arg1' => $arg1, 'arg2' => $arg2);
call_user_func_array('test', $params);
