I have a fairly complicated regular expression that was written for perl.
I've spent the last 4 days trying to convert it to PHP.
I guess I'm just that bright.
I can't even get the sub parts (between the || to work, much less the
conditionals
Would someone mind showing me how I can make this work in PHP?
Thanks
