Bug #74472 [Nab]: readdir strips leading and trailing quotes in a filename

Edit report at https://bugs.php.net/bug.php?id=74472&edit=1 ID: 74472 User updated by: james at workinout dot com Reported by: james at workinout dot com Summary: readdir strips leading and trailing quotes in a filename Status: Not a bug Type: Bug Package: Filesystem function related Operating System: Fedora PHP Version: 7.1.4 Block user comment: N Private report: N New Comment: escapeshellarg() works. after it adds back single quotes around the file then stat works. using echo shows the single quotes are added back. but as i said below, readdir() is stripping the quotes, otherwise, I would not need to use escapeshellarg. as someone said below, its better not to use quotes in filenames ..
