For a project I’ve been working on I needed to use preg_match quite a bit. But I got really tired of having to punch in several lines, so I cooked up this little snippet to pull out a specific match group.
<?php /** * Shortcut to doing regex without needing to worry about $matches * @param type $pattern * @param type $search * @param type $group */ function preg_search($pattern, $search, $group=1) { if (preg_match($pattern, $search, $matches)) { if (isset($matches[$group])) { return $matches[$group]; } return false; } return false; }
$pattern
and $search
work just like normal preg_match
. The $group
parameter tells it which matching group to return, if it exists. If it doesn’t exist, it returns false.
