note 18784 added to function.preg-grep

I wrote this little function to match the keys (rather than values) in an associative array to a pattern. Hope it helps some one. // function to grep keys of an array for a pattern // returns an array function grep_keys($pattern, $array) { $newarray = Array(); while( list($key, $val) = each($array)) { if(preg_match($pattern,$key)) $newarray[$key] = $val; } return $newarray; } -- http://www.php.net/manual/en/function.preg-grep.php http://master.php.net/manage/user-notes.php?action=edit+18784 http://master.php.net/manage/user-notes.php?action=delete+18784 http://master.php.net/manage/user-notes.php?action=reject+18784
