Question

The problem is easy to explain. What I want to do is to create an object, parameters and function calls based on $_POST variables.

$obj = new $_POST['object']['name']($_POST['object']['params']);

            return json_encode(
                 $obj->$_POST['function']['name']($_POST['function']['params'])
            );

The only problem here is that it gives the parameters as an array. And I want it to seperate the variables with a comma, like: $obj->function($var1 , $var2, $var3);. How can I achieve this?

The best way is to create object without arguments passed to constructor and initiate it using some other method. For example:

$obj = new $_POST['object']['name']();
$result = call_user_func_array(array($obj,'init'),$_POST['object']['params']);

Also, in PHP 5.4+ you can use this “hack”:

$reflection = new ReflectionClass($_POST['object']['name']);
$obj = $reflection->newInstanceWithoutConstructor();
call_user_func_array(array($obj,'__constructor'),$_POST['object']['params']);

But I advise you to change your architecture so you would be able to pass array to constructor “as is”.
