ID: 26381 Updated by: iliaa@php.net Reported By: spam at vrana dot cz -Status: Open +Status: Bogus Bug Type: Math related Operating System: Windows XP PHP Version: 4.3.3 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php For random numbers you MUST call srand() before rand(). Previous Comments: ------------------------------------------------------------------------ [2003-11-25 04:53:44] spam at vrana dot cz Unfortunately it behaves the same with Windows snapshots. For case it's not obvious from my fist comment - if I call srand() before rand() it works well. ------------------------------------------------------------------------ [2003-11-25 04:24:32] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Works fine for me within Windows XP, within Apache and CLI. ------------------------------------------------------------------------ [2003-11-24 08:21:33] spam at vrana dot cz Description: ------------ Function rand() without setting random seed by srand() returns always the same value. It doesn't work only on Windows PHP-CLI. As Windows Apache module and also on Linux PHP-CLI it works as it should. Reproduce code: --------------- echo rand(); Expected result: ---------------- (random value) Actual result: -------------- 24849 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26381&edit=1
