How to return only named groups with preg_match or preg_match_all?

Question

Example:

$string = \"This is some text written on 2010-07-18.\";
preg_match(\'|(?\\d\\d\\d\\d-\\d\\d-\\d\\d)|i\', $string, $arr_result);
print_r(         


        

Answer 1

You could use T-Regx and go with group() or namedGroups() which only returns named capturing groups.

\d\d\d\d-\d\d-\d\d)', 'i')->match($subject)->first(function ($match) {

    $date = $match->get('date'); 
    // 2010-07-18

    $groups = $match->namedGroups(); 
    // [
    //   'date' => '2010-07-18'
    // ]   
});
