From: laruence@php.net (Laruence)

Hi:
   if this change will  not revert, I will ask a more clearly error
message for this,
   I report a req, https://bugs.php.net/bug.php?id=3D55719,

     which is,  the error message should told user what the correct
argument list is.

   and also submitted a patch for this req.

  thanks
