Dec 06
This simple function will turn the poorly formatted phone numbers entered by users into a visually appealing set of numbers.
/**
* 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 = preg_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 </code>
