Dynamically invoke method / function

[Markus]

Say the name of the function is passed by GET.

How can we invoke the method?

EDIT: call_user_func() does the trick?

[Atli]

call_user_func() should work.

You could always use the eval function.
I would put a huge warning sign on the idea of calling functions from a variable passed by get tho!
Just imagine... page.php?func=unlink("~/*");
Dunno if that exact syntax actually works but something similar probably does.

Heya, Markus.

Consider validating your function name.

E.g.:

switch( $_GET['func'] )
{
    case '':
        $func = 'strip_tags';
    break;
 
    case 'strip_tags':
    case 'trim':
    case 'rot13':
        $func = $_GET['func'];
    break;
 
    default:
        $func = 'strip_tags';
    break;
}
 
echo $func($text);
 

[EDIT: I can't wait for that issetor operator....]

I'm not stupid guys ;]

Like an MVC, the class is passed through the url and the method follows.

Do you mean this...

if (function_exists($_GET["function"]))
$_GET["function"]();

You can change it for the function arguments too.

$_GET['func']();
Looks abit ugly, to me.
