note 25362 added to function.preg-match

The return type is listed as int, but all the examples show the return type being tested as boolean. Before thinking it through I wondered if it might return the number of pattern elements matched. My quick test returned the value 1 from an successful match on six pattern elements. Although you could construct a pattern where the the match succeeds with a variable number of subexpressions matched by marking entire subexpressions as optional, it doesn't make sense to think of it this way. Are there any other possible return codes aside from 0 or 1? -- http://www.php.net/manual/en/function.preg-match.php http://master.php.net/manage/user-notes.php?action=edit+25362 http://master.php.net/manage/user-notes.php?action=delete+25362 http://master.php.net/manage/user-notes.php?action=reject+25362
