I add this in httpd.conf : PassEnv TEMP Then the problem disappears. Hope that helps ! ------------------------------------------------------------------------ [2016-05-23 13:00:49] biloo1 at caramail dot com In same context, the tempnam function reproduce this bug : echo tempnam("", ""); returns: 'C:\Windows\A760.tmp' ------------------------------------------------------------------------ [2016-05-23 12:46:32] biloo1 at caramail dot com PHP 5.3.10 via CGI (Action application/x-httpd-php "/php/php-cgi.exe") Apache 2.2.29 Windows 7 Pro SP1 sys_get_temp_dir() returns path 'C:\Windows' My windows variables are set to '%SystemRoot%\TEMP' and '%USERPROFILE%\AppData\Local\Temp' BUT NOT TO 'C:\Windows' (%SystemRoot%) ------------------------------------------------------------------------ [2013-07-09 09:59:15] ab@php.net Ok, just tried it again with IIS+fastcgi+win8, it gives c:\windows\temp . The windows implementation uses this API function to determine the temporary dir http://msdn.microsoft.com/en-us/library/windows/desktop/aa364992(v=vs.85).aspx According to that docs, c:\windows is the very last fallback when none of TMP, TEMP, USERPROFILE has worked. Conclusion - this is neither PHP nor Win API issue, but an environment one. For 5.4 one of those environment variables has to be set, for 5.5+ additionally sys_temp_dir is usable. ------------------------------------------------------------------------ [2013-07-08 18:57:13] czarek dot tomczak at gmail dot com In the latest PHP 5.5.0 the temp directory on Windows 8 is "C:\Windows", just confirmed by one of the users. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
