Re: [PHP] validate phone numbers
There are so many combinations of European phone numbers, along with the
possible combinations of area codes, and hyphens or spaces may be used as
well, I wouldn't bother. If the phone number is critical, and important to
the person using your site, then treatitlike a password and have them enter
it twice. Although in that case they are likely to enter it correctly anyway.
One can only do so much.

RE: [PHP] validate phone numbers
i agree. there's NOTHING more annoying than a broken validation script when you're trying to enter valid, but weird, data. perhaps separate the form up into one box for the country code, one box for the number, and one box for any add'l information (extensions, automated prompt numbers, etc...), so that you'd only have to work at validating the actual number (and not any extraneous and oddly formatted info) > -Original Message- > From: Steve Werby [mailto:[EMAIL PROTECTED]] > Subject: Re: [PHP] validate phone numbers > > people enter #s in many > different formats and sometimes it's necessary to enter a # like > "011-817-972-1086 x103" or "817-972-1086, 1, 3, 12" if you're dealing with > business numbers with extensions or automated systems that have to be > traversed.

It would be helpful if you post a list of the range of phone numbers you are
encountering that you are having a problem with. Or I can get you started
by saying that I think you're regular expression is saying "beginning with
anything, then exactly 3 numbers, then anything, then exactly 3 numbers,
then anything, then ending in exactly 4 numbers". Changing a {3} to {3,4}
would mean "match 3-4 occurences of what's to the left". Hopefully that
will get you started, if you post some other numbers you want to pass
validation we can be of more assistance. regex are very powerful and I
recommend you add them to your training. That said, people enter #s in many
different formats and sometimes it's necessary to enter a # like
"011-817-972-1086 x103" or "817-972-1086, 1, 3, 12" if you're dealing with
business numbers with extensions or automated systems that have to be
traversed. So you may be better off not validating the phone #. YMMV.
