Edit report at https://bugs.php.net/bug.php?id=79254&edit=1 ID: 79254 Patch added by: cmb@php.net Reported by: franz dot zieris at gmail dot com Summary: CLI: getenv() w/o arguments not showing changes Status: Verified Type: Bug Package: PHP options/info functions Operating System: Windows ZTS PHP Version: 7.4.2 Block user comment: N Private report: N New Comment: The following pull request has been associated: Patch Name: Fix #79254: getenv() w/o arguments not showing changes On GitHub: https://github.com/php/php-src/pull/5167 Patch: https://github.com/php/php-src/pull/5167.patch Previous Comments: ------------------------------------------------------------------------ [2020-02-10 16:05:06] cmb@php.net Confirmed for ZTS builds. The problem is that ZTS builds use only SetEnvironmentVariable(), but not putenv() (because the latter is not thread-safe), but read the enviroment using environ, which only would reflect putenv() changes. ------------------------------------------------------------------------ [2020-02-10 14:35:22] franz dot zieris at gmail dot com Description: ------------ Calling getenv() without an argument does not reflect change made with putenv, but calling getenv() on a concrete variable *does*. The test script below produces the expected output on a Linux machine, but on my Windows machine the array difference is "array(0) { }".
