regex phone number

[eli03]

greetings,

i found this regex if to get a valid phone number,

This is a constant that helps in getting a valid phone number that does not need to be in a particular format. The following is a constant that matches the following US Phone formats:

Phone number can be in many variations of the following:
(Xxx) Xxx-Xxxx
(Xxx) Xxx Xxxx
Xxx Xxx Xxxx
Xxx-Xxx-Xxxx
XxxXxxXxxx
Xxx.Xxx.Xxxx

define( "REGEXP_PHONE", "/^(\(|){1}[2-9][0-9]{2}(\)|){1}([\.- ]|)[2-9][0-9]{2}([\.- ]|)[0-9]{4}$/" );


 

i found this on php manual , here is the link http://ph.php.net/manual/en/function.preg-match.php

my question is, how will i used that regex ?

[mtmosier]

if (preg_match(REGEXP_PHONE, $phone)) {
    //  Its a phone number
}

the regex doesn't work, the error is "Warning: Compilation failed: range out of order in character class at offset 32 " , any suggestion? i want to do similar things, get phone number in different format.

Guess I should've tested, eh? What's the world coming to when you can't simply trust code found in php.net's user comments section.

Actually the problem seems to have been just backslashes getting stripped out, by one forum or another.

define( "REGEXP_PHONE", "/^(\\(|){1}[2-9][0-9]{2}(\\)|){1}([\\.\\- ]|)[2-9][0-9]{2}([\\.\\- ]|)[0-9]{4}$/" );

i treid to used the regex, and nothing print, here is my code

<?php
$var="text text text call texttext 123-456-7896 or [phone]  text text text 1234447894 [phone] 451.254.1236 dsfdsfdsd 456-879-9874";
//preg_match_all("/(\d{3})-(\d{3})-(\d{4})/", $var, $match);
preg_match_all("/^(\(|){1}[2-9][0-9]{2}(\)|){1}([\.\- ]|)[2-9][0-9]{2}([\.\- ]|)[0-9]{4}$/", $var, $match);


  foreach ($match[0] as $u =>$eli) {
   echo $match[0][$u]."<br>";
}

?>

thanks

The "^" at the beginning of the expression, and the "$" at the end require that the entire string be a phone number. Remove these two and it should work.

Note that some of your phone numbers are invalid by this regex's definition, such as 123-456-7896.
