How do i validate all countries phone number with php

Question

有没有办法用php验证所有国家的电话号码

Answer 1

you can implement this by using preg_match, i dont think any automatic validation exist

By using a database for storing formats and then checking those with entered phonenumber

int preg_match ( string $pattern , string $subject [, array &$matches [, int $flags = 0 [, int $offset = 0 ]]] )

eg.,

<?php
// The "i" after the pattern delimiter indicates a case-insensitive search
if (preg_match("/php/i", "PHP is the web scripting language of choice.")) {
    echo "A match was found.";
} else {
    echo "A match was not found.";
}
?>

see this http://php.net/manual/en/function.preg-match.php

Take the information about country phone number starting codes from:
http://www.international-dialing-codes.net/
insert into database, create array, make while cycle where it will get information from DB, then create foreach.. something like that..
