Grabbing all the text in a text to the left of a token?

[dmccabe]

Ok I have this text:

 

User Name (Real Name)

 

I want to grab the text "User Name" and "Real Name" separately?

 

How can I split them, I know it has something to do with Strpos and Substr, but I just cant get it right or anywhere close, this is where I get before getting all kinds of  confused:

 

$pos = strpos($author, "(");
$name= substr($author, $pos, -1);

$text = "User Name (Real Name)";
$regex = preg_match("/^(.*)\s\((.*)\)$/", $text, $matches);
$username = $matches[1];
$realname = $matches[2];
