Edit report at https://bugs.php.net/bug.php?id=70139&edit=1 ID: 70139 User updated by: tomkrawc at gmail dot com Reported by: tomkrawc at gmail dot com Summary: is_link or DirectoryIterator->isLink don't work -Status: Feedback +Status: Assigned Type: Bug Package: Filesystem function related Operating System: Windows 7 64bit PHP Version: 5.5.27 Assigned To: cmb Block user comment: N Private report: N New Comment: I don't know what to say. Yesterday the script http://pastebin.com/6h1G6ku5 was creating such an output http://pastebin.com/Z4c4pUDs. Today it returns expected results. The code of @requinix results that way http://pastebin.com/3PxHQU30. So it is correct. I don't know why it works today... Previous Comments: ------------------------------------------------------------------------ [2015-07-29 00:08:16] requinix@php.net Wrote this and my Win 8.1 with PHPs 5.4.29, 5.5.13, 5.6.11 don't reproduce: is_file says no, is_dir and is_link say yes. Note that you will probably need an elevated command prompt to run mklink. <?php $tempnam = tempnam(sys_get_temp_dir(), "php"); unlink($tempnam); // tempnam created a file // expecting to see "symbolic link created for %s <<===>> C:\" // - /d to create a directory symlink // - /j to create a junction passthru("mklink /d " . escapeshellarg($tempnam) . " C:\\"); clearstatcache(); if (file_exists($tempnam)) { echo "Created directory {$tempnam}\n"; echo "- is_file: ", (is_file($tempnam) ? "yes" : "no"), "\n"; echo "- is_dir: ", (is_dir($tempnam) ? "yes" : "no"), "\n"; echo "- is_link: ", (is_link($tempnam) ? "yes" : "no"), "\n"; rmdir($tempnam) or printf("Failed to remove directory\n"); } else { echo "Directory {$tempnam} does not exist\n"; } ?> ------------------------------------------------------------------------ [2015-07-28 23:39:04] cmb@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report.
