In that case you may find Regex Coach (http://weitz.de/regex-coach/)
handy. It essentially does the match in real-time as you watch, and
shows you exactly what each part of the regex is matching.
Essentially, you paste the text to search through in the bottom pane,
and start typing the regex in the top pane. It makes writing regular
expressions enormously easier. It uses LISP to emulate Perl's regular
expressions (PHP in turn uses "Perl Compatible Regular Expressions"), so
sometimes it doesn't translate a hundred percent, but it's still an
enormous help.

Perfect, thanks very much. I think I'll probably die before I'm ever
handy with regex.

Is there a command to strip all non-alphanumerics form the beginning
and end of a string?
Ex.: '&^%kj.h,kj..*(' becomes 'kj.h,kj'
<?php
$text = ereg_replace( '^[^[:alnum:]]+', '', $text );
$text = ereg_replace( '[^[:alnum:]]+$', '', $text );
?>
Cheers,
