I'm running Grav CMS on a Linode Ubuntu 16.04 server where PHP7 (php-fpm + nginx) returns cached results when listing directory contents. I first encountered the problem with FilesystemIterator
, but it isn't limited to that class - the same problem appears when I use scandir
.
Basically what happens is that any time I sync new content to the server, whether I use rsync or FTP, PHP will return the old contents of a particular folder.I've tried calling clearstatcache
, but it didn't help – even if I called it from the appropriate PHP file, just before I scanned the directory.
touch
'ing the files to update their mtime doesn't help either. Restarting the php-fpm service does work, however.
Is it possible that PHP caches the contents of the directory in some other way? Could it be the file system that is fooling PHP somehow?
