Im pretty sure the double backslash is a typo. here are some regexps from a php5 class I use:

Intersting you should say that because I was told to escape my slashes in this case, otherwise I wouldn't have either. I've tested it and it works so...

well you have to escape the bslash if your using double quotes. there is a reason sane people (normally) write regexps in php using single quotes :-) php -r " echo '\d';" php -r ' echo "\n";' php -r " echo '\\d';" php -r ' echo "\n";' php -r ' echo "\\d";' php -r ' echo "\n";' php -r ' echo "\\\\d";' php -r ' echo "\n";' don't ask (me) why this is so. I just learn how from bitter experience :-), the why for greater mortals than I.

Thanks Jochem - all advice much appreciated.

you might curse me in the long term ;-)
