Okay. My regex skills are a little rusty, so forgive me if I'm overlooking something obvious here.

What I'm trying to do is create a regex pattern that will match text outside square brackets -- specifically, this is for PHP's preg_replace() function.

The pattern I have so far is (^|\])(.*?)?(\[|$)
The problem I'm having is that this pattern is matching the brackets as well as the text. Which, with that particular pattern, means it's working properly.

What I need to know now is how do I make it so the brackets are required in order to make a match, but aren't returned as part of the match.

Any help would be appreciated.

// What you want to replace
$replacements = array('[', ']');

// str_replace returns $string with [ and ] replaced by blanks, this is
// then the string that is returned by preg_replace when $pattern is matched
// within $string
preg_replace($pattern, str_replace($replacements, '', $string), $string);
