问题
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 records in a MySQL database.
The numbers are stored in the latter format for use elsewhere on the site and I would rather not change that format as it would require modifying a lot of code.
How would I go about this with PHP?
Thanks!
回答1:
$data = '+11234567890';
if( preg_match( '/^\+\d(\d{3})(\d{3})(\d{4})$/', $data, $matches ) )
{
$result = $matches[1] . '-' .$matches[2] . '-' . $matches[3];
return $result;
}

This is a US phone formatter that works on more versions of numbers than any of the current answers.
$numbers = explode("\n", '(111) 222-3333
((111) 222-3333
1112223333
111 222-3333
111-222-3333
(111)2223333
+11234567890
1-8002353551
123-456-7890 -Hello!
+1 - 1234567890
');
foreach($numbers as $number)
{
print preg_replace('~.*(\d{3})[^\d]{0,7}(\d{3})[^\d]{0,7}(\d{4}).*~', '($1) $2-$3', $number). "\n";
}
And here is a breakdown of the regex:
Cell: +1 999-(555 0001)
.* zero or more of anything "Cell: +1 "
(\d{3}) three digits "999"
[^\d]{0,7} zero or up to 7 of something not a digit "-("
(\d{3}) three digits "555"
[^\d]{0,7} zero or up to 7 of something not a digit " "
(\d{4}) four digits "0001"
.* zero or more of anything ")"
Updated: March 11, 2015 to use {0,7} instead of {,7}

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;
}

Assuming that your phone numbers always have this exact format, you can use this snippet:
$from = "+11234567890";
$to = sprintf("%s-%s-%s",
substr($from, 2, 3),
substr($from, 5, 3),
substr($from, 8));

Phone numbers are hard. For a more robust, international solution, I would recommend this well-maintained PHP port of Google's libphonenumber library.
Using it like this,
use libphonenumber\NumberParseException;
use libphonenumber\PhoneNumber;
use libphonenumber\PhoneNumberFormat;
use libphonenumber\PhoneNumberUtil;
$phoneUtil = PhoneNumberUtil::getInstance();
$numberString = "+12123456789";
try {
$numberPrototype = $phoneUtil->parse($numberString, "US");
echo "Input: " . $numberString . "\n";
echo "isValid: " . ($phoneUtil->isValidNumber($numberPrototype) ? "true" : "false") . "\n";
echo "E164: " . $phoneUtil->format($numberPrototype, PhoneNumberFormat::E164) . "\n";
echo "National: " . $phoneUtil->format($numberPrototype, PhoneNumberFormat::NATIONAL) . "\n";
echo "International: " . $phoneUtil->format($numberPrototype, PhoneNumberFormat::INTERNATIONAL) . "\n";
} catch (NumberParseException $e) {
// handle any errors
}
you will get the following output:
Input: +12123456789
isValid: true
E164: +12123456789
National: (212) 345-6789
International: +1 212-345-6789
I'd recommend using the E164 format for duplicate checks. You could also check whether the number is a actually mobile number or not (using PhoneNumberUtil::getNumberType()), or whether it's even a US number (using PhoneNumberUtil::getRegionCodeForNumber()).
As a bonus, the library can handle pretty much any input. If you, for instance, choose to run 1-800-JETBLUE through the code above, you will get
Input: 1-800-JETBLUE
isValid: true
E164: +18005382583
National: (800) 538-2583
International: +1 800-538-2583
Neato.
It works just as nicely for countries other than the US. Just use another ISO country code in the parse() argument.
回答6:
Here's my USA-only solution, with the area code as an optional component, required delimiter for the extension, and regex comments:
function formatPhoneNumber($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");
}

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;
}
回答8:
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.
回答9:
Try something like:
preg_replace('/\d{3}/', '$0-', str_replace('.', null, trim($number)), 2);
this would take a $number of 8881112222 and convert to 888-111-2222. Hope this helps.
回答10:
Another option - easily updated to receive a format from configuration.
$numbers = explode("\n", '(111) 222-3333
((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>';
}
// ************************************************************************

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 );

It's faster than RegEx.
$input = "0987654321";
$output = substr($input, -10, -7) . "-" . substr($input, -7, -4) . "-" . substr($input, -4);
echo $output;

Don't reinvent the wheel! Import this amazing library:
https://github.com/giggsey/libphonenumber-for-php
$defaultCountry = 'SE'; // Based on the country of the user
$phoneUtil = PhoneNumberUtil::getInstance();
$swissNumberProto = $phoneUtil->parse($phoneNumber, $defaultCountry);
return $phoneUtil->format($swissNumberProto, PhoneNumberFormat::INTERNATIONAL);
It is based on Google's library for parsing, formatting, and validating international phone numbers: https://github.com/google/libphonenumber

Notice I have this in a class lib, so thus the "self::validate_phone_number" call from the first function/method.
Notice line # 32 of the "validate_phone_number" function where I added the:
if ( !$valid['format'] ) {
return false;
} else {
to get me the false return needed if not valid phone number.
Still need to test this against more data, but working on current data, with current format and I'm using style '8' for this particular data batch.
Also I commented out the "extension" logic as I was constantly getting errors from it, seeing I do not have any of that info in my data.

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.

I know the OP is requesting a 123-456-7890 format, but, based on John Dul's answer, I modified it to return the phone number in parentheses format, e.g. (123) 456-7890. This one only handles 7 and 10 digit numbers.
function format_phone_string( $raw_number ) {
// remove everything but numbers
$raw_number = preg_replace( '/\D/', '', $raw_number );
// split each number into an array
$arr_number = str_split($raw_number);
// add a dummy value to the beginning of the array
array_unshift( $arr_number, 'dummy' );
// remove the dummy value so now the array keys start at 1
unset($arr_number[0]);
// get the number of numbers in the number
$num_number = count($arr_number);
// loop through each number backward starting at the end
for ( $x = $num_number; $x >= 0; $x-- ) {
if ( $x === $num_number - 4 ) {
// before the fourth to last number
$phone_number = "-" . $phone_number;
}
else if ( $x === $num_number - 7 && $num_number > 7 ) {
// before the seventh to last number
// and only if the number is more than 7 digits
$phone_number = ") " . $phone_number;
}
else if ( $x === $num_number - 10 ) {
// before the tenth to last number
$phone_number = "(" . $phone_number;

// concatenate each number (possibly with modifications) back on
