#30315 [Opn]: big integers don't overflow

ID: 30315 Updated by: jorton@php.net Reported By: tokul at users dot sourceforge dot net Status: Open Bug Type: Variables related Operating System: Linux PHP Version: 5.0.2 New Comment: I would argue that backwards compatibility is about making guarantees and not breaking them. It's not about simply ensuring that all behaviour remains exactly the same forever, otherwise you can't change anything at all. But no guarantee was broken in this change. Previous Comments: ------------------------------------------------------------------------ [2004-10-05 14:48:28] derick@php.net But it's still breaking backward compatibility, and that is also important. IMO this should just work like it did before. ------------------------------------------------------------------------ [2004-10-05 14:43:30] jorton@php.net PHP never guaranteed that integers larger than 2^31 wrap negative. It has never been true on a 64-bit platform, for example; there, your code will have always printed "3725722773". I don't think this is a PHP bug. ------------------------------------------------------------------------ [2004-10-04 10:03:43] derick@php.net You didn't mention that before ;-) So no, then this is ofcourse a bug. ------------------------------------------------------------------------ [2004-10-04 08:58:11] tokul at users dot sourceforge dot net Have you checked php behaviour in other php versions? I have also tested 4.1.2, 4.3.9 and 5.0.1. This happens only on 5.0.2. I just need to know, if this is a bug or default behaviour in future php versions. ------------------------------------------------------------------------ [2004-10-04 08:39:49] derick@php.net Sorry, but your problem does not imply a bug in PHP itself.
