Format Phone Number Fields with PHP

Filed under: PHP,The Coding World — admin @ 1:39 pm

Below is a function I wrote to take a phone number entered by a user and convert it into a desired format. The one shown below is 555-555-5555.

View Code PHP

function phn_numb($numb) {
if (!is_numeric(substr($numb, 0, 1)) &amp;&amp; !is_numeric(substr($numb, 1, 1))) { return $numb; }
 
$chars = array(' ', '(', ')', '-', '.');
$numb = str_replace($chars, "", $numb);
if (strlen($numb) &gt; 10) {
//you must dial "1" before dialing this number
$numb = substr($numb, 0, 1).'-'.substr($numb, 1, 3).'-'.substr($numb, 4, 3).'-'.substr($numb, 7, 4);
}
else
{
$numb = substr($numb, 0, 3).'-'.substr($numb, 3, 3).'-'.substr($numb, 5, 4);
}
 
return $numb;
}

Therefore to see it in action:

View Code PHP

$phonenumber = 2345678901;
 
echo phn_num($phonenumber);
 
//the resulting echo would be 234-567-8901
