Bug #70651 [Nab]: Inconsistent usage of Current Working Directory

Edit report at https://bugs.php.net/bug.php?id=70651&edit=1 ID: 70651 User updated by: deivid dot garcia dot garcia at gmail dot com Reported by: deivid dot garcia dot garcia at gmail dot com Summary: Inconsistent usage of Current Working Directory Status: Not a bug Type: Bug Package: Directory function related Operating System: Windows/IIS/FastCGI PHP Version: 7.0.0RC4 Block user comment: N Private report: N New Comment: There was too much info in the post... please reconsider looking at the *first* result: is_dir(sites/all): false is_dir(sites/default): false is_file(index.php): true These files/folders do exist and are under the same directory, all extensions disabled (only php core). So it is using one CWD for is_dir and another CWD for is_file? Makes no sense. And on the next run, with the same setup, index.php is reported as FALSE in the shutdown functions when nothing has changed. So on one run in shutdown is_file(index.php) returns false, on the other one is_file(index.php) returns true, and nothing has changed. Previous Comments: ------------------------------------------------------------------------ [2015-10-07 14:06:04] ab@php.net Thanks for the report. This behavior is documented and is unlikely to be changed. PHP depends on the C runtime in cases like this. Besides SAPIs changing CWD, any external extension could do it. That's where PHP core is not in control of this kind of change. An obvious solution in many cases is just using absolute paths. Thanks. ------------------------------------------------------------------------ [2015-10-06 15:15:21] deivid dot garcia dot garcia at gmail dot com Just as a final note, having the current working directory change on shutdown functions is an unpleasant but described behaviour in the PHP docs for some web servers. But I expect is_dir and is_file to make a consistent usage of what the current working directory is. ------------------------------------------------------------------------ [2015-10-06 15:11:05] deivid dot garcia dot garcia at gmail dot com Using reroute_enabled = 1 in the php ini setting for the Wincache extension yields further inconsistent results.
