HELP WITH CODE

Im trying to make it so it will work like this
/documentedit <Name> * <Text>

Will this work?

$name = implode(" ", $args);
$msg = implode("*", $args);

What do you want it to work like?

Like umm
/edit name * text

I would use this:
$params=explode ("*", implode (" ", $args));
file_put_contents ($this->dir.$params[0], $params[1]);

Work yourself if you want the file contents to be able to contain characters of "*".
