警告:在第17行中为C:\ wamp \ www \ eCardScript \ ecard_lib.php中的foreach()提供了无效的参数 * 警告: *在C:\ wamp \ www \ eCardScript \ ecard_lib.php中，在第21行

include('htmlMimeMail.php');

function getPostGetVars() {
  global $HTTP_POST_VARS,$HTTP_GET_VARS;
  foreach ($HTTP_POST_VARS as $key => $value) { // This is Line 17
    global $$key;
    $$key = $value;
  }

}
?>
