You don't have to write a new function, <?php call_user_func_array(array($obj, $method_name), $params); ?> works pretty fine! (to my mind, 'eval' fucntion should be avoided almost all the time)

<?php

/**

function call_object_method_array($func, $obj, $params=false){
    if (!
method_exists($obj,$func)){       
       
// object doesn't have function, return null
       
return (null);
    }
   
// no params so just return function
   
if (!$params){
        return (
$obj->$func());

// build eval string to execute function with parameters
