Extracting matches from php regex

Question

In perl regex we can extract the matched variables, ex below.

   # extract hours, minutes, seconds
   $time =~ /(\\d\\d):(\\d\\d):(\\d\\d)/; # match hh:mm

Check the php manual

int preg_match ( string $pattern , string $subject [, array &$matches [, int $flags [, int $offset ]]] )

If matches is provided, then it is filled with the results of search. $matches[0] will contain the text that matched the full pattern, $matches1 will have the text that matched the first captured parenthesized subpattern, and so on.

$subject = "E:contact@customer.com I:100955";
$pattern = "/^E:(?\w+) I:(?\d+)$/";
if (preg_match($pattern, $subject,$matches)) {
    print_r($matches);
}
