Formatting Phone Numbers in PHP

Question

I am working on an SMS app and need to be able to convert the sender\'s phone number from +11234567890 to 123-456-7890 so it can be compared to re

Answer 1

Here's my USA-only solution, with the area code as an optional component, required delimiter for the extension, and regex comments:

function formatPhoneNumber($s) {
$rx = "/
    (1)?\D*     # optional country code
    (\d{3})?\D* # optional area code
    (\d{3})\D*  # first three
    (\d{4})     # last four
    (?:\D+|$)   # extension delimiter or EOL
    (\d*)       # optional extension
/x";
preg_match($rx, $s, $matches);
if(!isset($matches[0])) return false;

$country = $matches[1];
$area = $matches[2];
$three = $matches[3];
$four = $matches[4];
$ext = $matches[5];

$out = "$three-$four";
if(!empty($area)) $out = "$area-$out";
if(!empty($country)) $out = "+$country-$out";
if(!empty($ext)) $out .= "x$ext";

// check that no digits were truncated
// if (preg_replace('/\D/', '', $s) != preg_replace('/\D/', '', $out)) return false;
return $out;
}

And here's the script to test it:

$numbers = [
'3334444',
'2223334444',
'12223334444',
'12223334444x5555',
'333-4444',
'(222)333-4444',
'+1 222-333-4444',
'1-222-333-4444ext555',
'cell: (222) 333-4444',
'(222) 333-4444 (cell)',
];

foreach($numbers as $number) {
    print(formatPhoneNumber($number)."<br>\r\n");
}

Answer 2

this takes 7, 10 and 11 digit, removes additional characters and adds dashes by going right to left through the string. change the dash to a space or dot.

$raw_phone = preg_replace('/\D/', '', $raw_phone);
$temp = str_split($raw_phone);
$phone_number = "";
for ($x=count($temp)-1;$x>=0;$x--) {
    if ($x === count($temp) - 5 || $x === count($temp) - 8 || $x === count($temp) - 11) {
        $phone_number = "-" . $phone_number;
    }
    $phone_number = $temp[$x] . $phone_number;
}
echo $phone_number;

Answer 3

This function will format international (10+ digit), non-international (10 digit) or old school (7 digit) phone numbers. Any numbers other than 10+, 10 or 7 digits will remain unformatted.

function formatPhoneNumber($phoneNumber) {
    $phoneNumber = preg_replace('/[^0-9]/','',$phoneNumber);

    if(strlen($phoneNumber) > 10) {
        $countryCode = substr($phoneNumber, 0, strlen($phoneNumber)-10);
        $areaCode = substr($phoneNumber, -10, 3);
        $nextThree = substr($phoneNumber, -7, 3);
        $lastFour = substr($phoneNumber, -4, 4);

        $phoneNumber = '+'.$countryCode.' ('.$areaCode.') '.$nextThree.'-'.$lastFour;
    }
    else if(strlen($phoneNumber) == 10) {
        $areaCode = substr($phoneNumber, 0, 3);
        $nextThree = substr($phoneNumber, 3, 3);
        $lastFour = substr($phoneNumber, 6, 4);

        $phoneNumber = '('.$areaCode.') '.$nextThree.'-'.$lastFour;
    }
    else if(strlen($phoneNumber) == 7) {
        $nextThree = substr($phoneNumber, 0, 3);
        $lastFour = substr($phoneNumber, 3, 4);

        $phoneNumber = $nextThree.'-'.$lastFour;
    }

    return $phoneNumber;
}

Answer 4

Here's a simple function for formatting phone numbers with 7 to 10 digits in a more European (or Swedish?) manner:

function formatPhone($num) {
    $num = preg_replace('/[^0-9]/', '', $num);
    $len = strlen($num);

    if($len == 7) $num = preg_replace('/([0-9]{2})([0-9]{2})([0-9]{3})/', '$1 $2 $3', $num);
    elseif($len == 8) $num = preg_replace('/([0-9]{3})([0-9]{2})([0-9]{3})/', '$1 - $2 $3', $num);
    elseif($len == 9) $num = preg_replace('/([0-9]{3})([0-9]{2})([0-9]{2})([0-9]{2})/', '$1 - $2 $3 $4', $num);
    elseif($len == 10) $num = preg_replace('/([0-9]{3})([0-9]{2})([0-9]{2})([0-9]{3})/', '$1 - $2 $3 $4', $num);

    return $num;
}

Answer 5

Another option - easily updated to receive a format from configuration.

$numbers = explode("\n", '(111) 222-3333
((111) 222-3333
1112223333
111 222-3333
111-222-3333
(111)2223333
+11234567890
    1-8002353551
    123-456-7890   -Hello!
+1 - 1234567890
');
foreach( $numbers AS $number ){
  echo comMember_format::phoneNumber($number) . '<br>';
}

// ************************************************************************
// Format Phone Number
public function phoneNumber( $number ){
  $txt = preg_replace('/[\s\-|\.|\(|\)]/','',$number);
  $format = '[$1?$1 :][$2?($2):x][$3: ]$4[$5: ]$6[$7? $7:]';
  if( preg_match('/^(.*)(\d{3})([^\d]*)(\d{3})([^\d]*)(\d{4})([^\d]{0,1}.*)$/', $txt, $matches) ){
    $result = $format;
    foreach( $matches AS $k => $v ){
      $str = preg_match('/\[\$'.$k.'\?(.*?)\:(.*?)\]|\[\$'.$k.'\:(.*?)\]|(\$'.$k.'){1}/', $format, $filterMatch);
      if( $filterMatch ){
        $result = str_replace( $filterMatch[0], (!isset($filterMatch[3]) ? (strlen($v) ? str_replace( '$'.$k, $v, $filterMatch[1] ) : $filterMatch[2]) : (strlen($v) ? $v : (isset($filterMatch[4]) ? '' : (isset($filterMatch[3]) ? $filterMatch[3] : '')))), $result );
      }
    }
    return $result;
  }
  return $number;
}

Answer 6

I see this being possible using either some regex, or a few substr calls (assuming the input is always of that format, and doesn't change length etc.)

something like

$in = "+11234567890"; $output = substr($in,2,3)."-".substr($in,6,3)."-".substr($in,10,4);

should do it.
