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

Edit report at https://bugs.php.net/bug.php?id=70651&edit=1 ID: 70651 Updated by: ab@php.net Reported by: deivid dot garcia dot garcia at gmail dot com Summary: Inconsistent usage of Current Working Directory -Status: Open +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: 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.

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.
