用PHP格式化电话号码

Question

I have a phone number that is stored in a database like:

5555555555

I want to format this like:

(555) 555-5555

using php i have the following code:

<?php
  $data = $order['contactphone'];

  if(  preg_match( '/^\+\d(\d{3})(\d{3})(\d{4})$/', $data,  $matches ) )
      {
        $result = $matches[1] . '-' .$matches[2] . '-' . $matches[3];
        echo $result;
      }
?>

This returns nothing at all once so ever. Not even an error. How can I do this?

Answer 1

This is what I've used in the past. Not as elegant as a regex I suppose but it can get the job done:

/**
 * Formats a phone number
 * @param string $phone
 */
static public function formatPhoneNum($phone){
  $phone = preg_replace("/[^0-9]*/",'',$phone);
  if(strlen($phone) != 10) return(false);
  $sArea = substr($phone,0,3);
  $sPrefix = substr($phone,3,3);
  $sNumber = substr($phone,6,4);
  $phone = "(".$sArea.") ".$sPrefix."-".$sNumber;
  return($phone);
}

ps I didn't write this, just something I grabbed six years ago.

Change regex from '/^\\+\\d(\\d{3})(\\d{3})(\\d{4})$/' to '/^(\\d{3})(\\d{3})(\\d{4})$/' , ie:

if(  preg_match( '/^(\d{3})(\d{3})(\d{4})$/', $data,  $matches ) )
      {
        $result = '(' . $matches[1] . ') ' .$matches[2] . '-' . $matches[3];
        echo $result;
      }
