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         


        

Answer 1

Try using the named subpattern syntax of preg_match:

\w+): (?\d+)/', $str, $matches);

// Before PHP 5.2.2, use this:
// preg_match('/(?P\w+): (?P\d+)/', $str, $matches);

print_r($matches);

?>

Output:

 Array (
     [0] => foobar: 2008
     [name] => foobar
     [1] => foobar
     [digit] => 2008
     [2] => 2008 )
