PHP > Format Phone Number
Lets face it, visitors to our web sites are stupid (not you of course). People tend not to enter information correctly. This function will turn the poorly formatted phone numbers entered by users into a visually appealing set of numbers.
<?php
/**
* FORMATPHONE
* Converts phone numbers to the formatting standard
*
* @param String $num A unformatted phone number
* @return String Returns the formatted phone number
*/
function formatPhone($num)
{
$num = ereg_replace('[^0-9]', '', $num);
$len = strlen($num);
if($len == 7)
$num = preg_replace('/([0-9]{3})([0-9]{4})/', '$1-$2', $num);
elseif($len == 10)
$num = preg_replace('/([0-9]{3})([0-9]{3})([0-9]{4})/', '($1) $2-$3', $num);
return $num;
}
// echo formatPhone('1 208 - 386 2934');
// will print: (208) 386-2934
?>
