To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2018-05-11 14:08:50] tumul dot kumar at veneratech dot com #spam2 at rhsoft dot net- Well this is the new feature of php 7.1 (long path window support), hence it must work on windows 2008 server r2 as well. In C++, with some windows API it is possible to access and create new files on long path in the same window version.( NO Limitation Of OS). Therefore php must have access as well. It is not documented anywhere that this feature is not available for this window version(Server 2008 R2 SP1). Our product provide support on this window version, hence updating window won't work for us. ------------------------------------------------------------------------ [2018-05-11 12:35:12] spam2 at rhsoft dot net when you say it works in never windows versions it's obvisouly a limitation of the underlying OS and PHP hardly can do anything about it - why do you not upgrade the OS (which is already out of support and has only extended support until 2020) or just don't use that long filenames? ------------------------------------------------------------------------ [2018-05-11 12:27:17] tumul dot kumar at veneratech dot com Description: ------------ I'm using Apache 2.4.29 (Win 64), Php 7.1.12. I'm unable to use php functions such as file_exists() for long file path (having length more than 259) Whereas it is feature of Php 7.1 which works fine with Windows 10. Support must be in windows server 2008 r2 sp1 as it is not written anywhere that php 7.1 or Apache 2.4.29 (Win 64) don't support long file path feature for this window version. Test script: --------------- <?php //You may give any long path having length of more than 259 characters echo file_put_contents("C:\ProgramData\Pulsar\Jobs_Report\Pul0510_112_third - Copddddddddddddddddddddddddddddyssssssssssssssslllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllxyz\abc.txt"); ?> Expected result: ---------------- If path is accessible it must return 1, otherwise 0 Actual result: -------------- Apache is being restarted. In apache error log, following Error message is being printed - ([Wed May 09 19:21:03.822918 2018] [mpm_winnt:notice] [pid 3776:tid 328] AH00428: Parent: child process 5360 exited with status 255 -- Restarting) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76327&edit=1
