Req #75000 [Com]: getcwd() does not raise error when it fails

Edit report at https://bugs.php.net/bug.php?id=75000&edit=1 ID: 75000 Comment by: marco dot agnoli at me dot com Reported by: marco dot agnoli at me dot com Summary: getcwd() does not raise error when it fails Status: Open Type: Feature/Change Request Package: *General Issues Operating System: OS X PHP Version: 7.1.7 Block user comment: N Private report: N New Comment: Same can be said for the realpath function: ``` <?php error_reporting(E_ALL); var_dump(realpath('non-existing-path')); ?> ``` realpath() expects a valid path, so why not raise an error when no valid path was specified? Previous Comments: ------------------------------------------------------------------------ [2017-07-28 06:09:04] marco dot agnoli at me dot com Description: ------------ Some functions like chdir() raise an error when they fail, but others like getcwd() don't. I don't see why getcwd() should not raise an error. This makes catching errors more painful than it should be. Test script: --------------- <?php var_dump(getcwd()); // Remove traversal permission for the current directory system('chmod -x '.escapeshellarg(__DIR__)); /** * I would expect an error here * because getcwd() returns false here. */ var_dump(getcwd()); // Restore traversal permission system('chmod +x '.escapeshellarg(__DIR__)); ?> Expected result: ---------------- A warning from PHP that getcwd() failed. Actual result: -------------- getcwd() silently returns false. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75000&edit=1
