Calling call_user_func in preg_replace_callback

Orc · 01-22-2009, 12:49 PM

I need to use it to access object methods, how would I do this with preg_replace_callback?

I was thinking maybe using create_function and calling it using the classname and the method i want.

ClassName::Method() that sort of thing

Do you mean something like this?

php Code:

class TalkPHP_Callback
{
    public function get($aCaptured)
    {
        return $aCaptured[1];
    }
}

$pCallback = new TalkPHP_Callback();
echo preg_replace_callback('~I Love (.+)~', array($pCallback, 'get'), 'I Love TalkPHP');

Yes but it keeps saying argument 2 of preg_replace_callback is an invalid callback. I used create_function() and that seems to be doing something, I haven't tested all the code of that yet, so I'll get back on to this topic.
