formatting a phone number 1

[captlid]

$phone = '6467897654';
$phone = ereg_replace("([0-9]{3})([0-9]{3})([0-9]{4})", "(\1) \2-\3", $phone);

the output comes out like
(
) -

need phone number to look like (646)789-7654
And is there any difference between regex on windows and linux?

1. Start using PCRE instead of POSIX.
2. Adjust your pattern:

$phone = '6467897654';
$phone = preg_replace("/(\d{3})(\d{3})(\d{4})/", "(\\1) \\2-\\3", $phone);
echo($phone);

Note:
Escaping of backreferences is necessary when used in double quotes since the backslash has to be escaped in double quotes. Single quotes need no escaping:

$phone = '6467897654';
$phone = preg_replace("/(\d{3})(\d{3})(\d{4})/", '(\1) \2-\3', $phone);
echo($phone);

thanks that worked like a charm, I am guessing pcre has better cross compatibility?

The preg_* family of functions offer a number of advantages over the ereg_* family. See the chapter opening page for the ereg_* family (The "Tip" and "Warning" sections at the top of

http://www.php.net/manual/en/ref.regex.php)

for more information.
