Re: Pushing array onto array

James, My question had more to do with why the authors would give this usage when array_push is not documented to behave so (as you correctly described). Were they describing an earlier version of array_push? A simple buggy example? A typo perhaps? Since the authors Hughes and Zmievski are big names in PHP, though mortals like you and me, I'm inclined to think they were thinking about something. ----- Original Message ----- From: "Jason Wong" <php-general@gremlins.biz> To: <php-general@lists.php.net> Sent: Sunday, August 03, 2003 1:27 AM Subject: Re: [PHP] Pushing array onto array > On Sunday 03 August 2003 13:02, Hank TT wrote: > > Well, I might have been more specific about their example, since not > > everyone has the book.
