I have been struggling with a javascript regex validation for U.S.
phone numbers all afternoon. This is part of Manuel Lemos' Formsgen
class. This is limited to the 7 digit number sans 3 digit area code. To
be complete, the regex should disallow a phone number that begins with
0 or 1, 555 or any digit followed by 11. Here is the regex I'm using:
^(?!\d[1]{2}|[5]{3})([2-9]\d{2})([-])\d{4}$
start yourself in a controlled environment, instead of trying to
comeup with the endless ways a number can be formated and remove
all non digits, then simply test the condistion of the string
if substr(0,1) == 0 || substr(0,1) == 1
fail
if substr(0,3) == 555
fail
if substr(1,2) == 11
fail
if strlen != 7
fail

First, let me assure you that this is not one of those shady pyramid schemes
you've been hearing about. No, sir. Our model is the trapezoid!

[PHP] Regex (Phone Number)
I have been struggling with a javascript regex validation for U.S.
phone numbers all afternoon. This is part of Manuel Lemos' Formsgen
class. This is limited to the 7 digit number sans 3 digit area code. To
be complete, the regex should disallow a phone number that begins with
0 or 1, 555 or any digit followed by 11. Here is the regex I'm using:
^(?!\d[1]{2}|[5]{3})([2-9]\d{2})([-])\d{4}$
Manual Lemos indicated to me in an offline post that this should throw
a javascript runtime error because of the (? at the beginning of the
regex. I have tested it in over a dozen different browsers (Windows and
Mac) and the only one that throws the runtime error is IE on the Mac.
All others catch the errors I am trying to trap for with no runtime
errors. Can this regex be improved on or do I have to live with the
idiosyncratic behavior of Mac IE?
Thanks.
