RE: [PHP] Why would this eregi() function not work?

Hmmm... but I don't think I want to get too strict. I mean, if I can write the code to make sure the domain doesn't start or end with the hyphen, but can have one in between, then cool. But I think that would require more expression footwork than I'm capable of at this point. > I truly wish that I could point you to a canonical reference on the > matter, but such a thing escapes me... > http://www.opengroup.org/onlinepubs/7908799/xbd/re.html > ... which may be helpful. That's a pretty hefty read, but it looks useful to have around for a reference. Thanks! -- Cheers! Dave G ml@autotelic.com
