eval() issue

Hey all,

I'm new here and like to join the community to ask & answer!
From the netherlands as a airline pilot student and part-time php programmer :)

At my current project I got a situation in which I call a method from a child class and the parameter's are also defined in a config file. So using the config file info I build up the correct argument order, the variables are defined before that. Now I wanna use eval() to call my method but I get the following error:

Quote:

A PHP Error was encountered

Severity: 4096

Message: Object of class Rapport could not be converted to string

Filename: controllers/rapport.php

Line Number: 62

The code:

PHP Code:


			
//argumenten ophalen

                $arguments = $rapportages[$rapportage]['arguments'];



                //argumenten definen

                foreach($arguments as $arg) {

                    $$arg = false;

                }

                

                //daadwerkelijk bekende argument definen

                $$sorteer_methode = $sorteer_optie;

                

                //argumentvolgorde maken voor eval()

                $arg_order = '';

                foreach($arguments as $arg) {

                    $arg_order .= '$' . $arg . ', ';

                }

                $arg_order = substr($arg_order, 0, -2);

                

                //functie aanroepen

                eval("$this->$method($arg_order)");

$sorteer_optie is the argument I know and the others are already set false, this all seems ok but the eval() call doesn't work.
Think I need to escape it in some way but just putting a backward slash in front of $this won't work..

Thanks in advance!
