It actually returns the number of times the expression was found, but it will always be 0 or 1, because it stops after the first time the expression was found (as opposed to preg_match_all). I know, tomayto, tomahto.

Also please note that using regular expressions in that case is a huge overuse.

And that if a third argument is given `, $arrow, $matches)` it will be populated with the match information (array).
