Mam błąd w wyrażeniu regularnym ale nie wiem co jest źle. Potrzebuję dla 
tekstu (kodu w PHP):

private $data, $invalid;

wydobyć identyfikatory tzn. napisy data i invalid.
Robię to tak:

preg_match_all("/(static)?\\s*(private|protected|public)\\s+(static)?\\s*(\\\$([A-Za-z0-9_]+),?\\s*)+\\s*[^\\(]/", 
'private $data, $invalid;', $matches, PREG_OFFSET_CAPTURE);
var_dump($matches[5]);

array(1) {
   [0] =>
   array(2) {
     [0] =>
     string(7) "invalid"
     [1] =>
     int(16)
   }
}

Nie rozumiem dlaczego w wynikach nie mam napisu data.
