#37908 [NEW]: putenv() variables not reset at the end of the script

From: php at raj dot homelinux dot com Operating system: Linux 2.6 PHP version: 4.4.2 PHP Bug Type: Apache2 related Bug description: putenv() variables not reset at the end of the script Description: ------------ putenv() claims that the env variables are reset to their original values when the script exits. HOwever, this doesn't seem to be happening - as a result, if the env var TZ is set from a php script, it affects apache2 logs, changing the timestamp for all subsequent gets served by the process that ran this php script which set TZ. Reproduce code: --------------- set $timezone different from server timezone and run: putenv("TZ=".$timeZone); -- then do a few more gets and check the apache logs, you will see something like: xx.xx.xx.xx - - [19/Jun/2006:23:05:18 -0400] "GET ..." xx.xx.xx.xx - - [19/Jun/2006:23:05:18 -0400] "GET ..." xx.xx.xx.xx - - [20/Jun/2006:13:05:11 +1000] "GET ..." (see how the timestamp in the apache log flipped from -0400 to +1000.. thats the problem) Expected result: ---------------- Timestamps should remain consistent Actual result: -------------- Timestamps are not consistent (see example above) -- Edit bug report at http://bugs.php.net/?id=37908&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37908&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37908&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37908&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37908&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37908&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37908&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37908&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37908&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37908&r=support Expected behavior: http://bugs.php.net/fix.php?id=37908&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37908&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37908&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37908&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37908&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37908&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37908&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37908&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37908&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37908&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37908&r=mysqlcfg
