how to save function arguments into a variable in PHP

Question

Is there a way to save the arguments I am going to use in a function into a variable?

Example, if a function requires:

function foo($string, $callback_function) {
    //
}

How can I save

 $arguments = $string, $callback()

So that I can

foo($arguments)

Is this possible? How? And what does this method called?

Thank you very much

use call_user_func_array http://php.net/manual/en/function.call-user-func-array.php

<?php
$arguments=array($string,$callback);
call_user_func_array('foo',$arguments);

are there any other method? because the function is a method of a class Model::blah()->foo($arguments); ?

You can call static methods on classes like so: call_user_func_array('Model::blah', $arguments); And on instantiated objects by passing an array: call_user_func_array(array($model,'blah'), $arguments);
