Dear List -
Thank you for all your help in the past.
Here is another one....
I would like to have a regex which would validate that a telephone
number is in the format xxx-xxx-xxxx.
Thanks.

Also remove your stupid Email filter.
If you need a email filter, you should not be on this list or learn to setup
rules one.

You can't, phone numbers are more complex then that. You could use \d{3}-\d{=
3}-\d{4} to match that basic pattern for all numbers though.

Congrats. People in Hell would like ice water. Now we all know
that everyone wants something. ;-P
Really, this isn't a PHP question, but rather one of regular
expressions. That said, something like this (untested) should work:
$numbers =3D array(
'123-456-7890',
'2-654-06547',
'sf34-asdf-',
'abc-def-ghij',
'555_555_5555',
'000-000-0000',
'8007396325',
'241-555-2091',
'800-555-0129',
'900-976-739',
'5352-342=3D452',
'200-200-2000',
);
foreach ($numbers as $n) {
echo $n.(validate_phone($n) ? ' is ' : ' is not ').'a valid
US/Canadian telephone number.'.PHP_EOL;
}
function validate_phone($number) {
if (preg_match('/^[2-9]{1,}[0-9]{2,}\-[2-9]{1,}[0-9]{2,}\-[0-9] {4,}=
$/',trim($number)))
{
return true;
}
return false;
}
?>

Hi Ethan,
Could you do a string compare and check at certain characters for a
dash?
IE:
check the second character to see if it is a dash for 1-800...
if that is not a dash, check the fourth character for a dash, 469-9...
then the other places where dashes would be based on those two
characters.
You may have to investigate how international numbers would work and
adjust appropriately, but for the US, that should work.
Then just send an error message when it isn't like you want.

You could also help them out a little with something like..
$phone = str_replace("(", "", $phone);
$phone = str_replace(")", "-", $phone);

Josh -
I used use \d{3}-\d{3}-\d{4}.
It works beautifully!!
FYI [to all the list] -- I thank all for their input. I only needed
US phones, and I am forcing the user of the form to conform to
xxx-xxx-xxxx as the input format.

Just keep in mind that invalid numbers will also pass that check,
such as 000-000-0000 or 123-456-6789. That's why my example was a bit
more involved.

Regex is over-kill.
$phoneNum = preg_replace("%\D%", '', $phoneNum);//Remove everything except digits
$phoneNum = ltrim($phoneNum,'1');//Remove leading 1s
if(strlen($phoneValue) != 10)
{
throw new Exception("Phone number must be 10 digits, without leading a 1. Check
your entry carefull");
}

I guess, this will work fine
ereg('[0-9]{3}-[0-9]{3}-[0-9]{4}', $phone_number);

Not quite. Plus, all ereg* functions have been deprecated for
some time now.

Actually...
Specified here [1] it says that the {1,} is the same as '+'. I think you should
drop the comma. If you don't this would be valid 844-2345-123456
^[2-9]{1,}[0-9]{2,}\-[2-9]{1,}[0-9]{2,}\-[0-9]{4,}$
should be
^[2-9]{1}[0-9]{2}\-[2-9]{1}[0-9]{2}\-[0-9]{4}$

Bah, you're absolutely correct. Force of habit with the commas.
I didn't even notice the sample test cases I put into that test array
didn't check for more than the number of digits per field, either.
Good catch, Jim, and Happy New Year.
