Bug #79884 [NEW]: PHP_CONFIG_FILE_PATH is meaningless

From: cmb Operating system: Windows PHP version: 7.3Git-2020-07-22 (Git) Package: PHP options/info functions Bug Type: Bug Bug description:PHP_CONFIG_FILE_PATH is meaningless Description: ------------ On Windows, PHP_CONFIG_FILE_PATH is determined during *build* time (using the environment variable SystemRoot, and falling back to an empty string if that is not set). However, when constructing the php_ini_search_path during *run* time, this constant is ignored, and instead the results of GetWindowsDirectory() and GetSystemWindowsDirectory() are added to the INI search path[1]. While in the most typical case either is C:\Windows, both may actually differ; thus, PHP_CONFIG_FILE_PATH must not be set to any hard-coded value during *build* time.
