PHP5.4 provides Session Upload Progress indication. I have noticed that it works, but only if session.save_handler is set to files, and session.name is not modified. As soon as I modify these values, the superglobal $_SESSION['upload_progress_<key>'] is empty / not set.
Is it possible to provide session upload progress indication, but with custom session handling? Even save handler memcache does not work...
分享 As @Marc points out: Session Upload Progress indication is running while the upload is ongoing, and before control is handed over to a user's PHP code. As a result, the php upload handler uses configuration data set in the .ini files, and can only use modules that are available at that time.
It is possible to use the memcache save-handler, or specify a different session name, as long as everything is configured in an .ini file:
session.save_handler = memcache
session.save_path = "tcp://198.51.100.1:11211?persistent=1&weight=1&timeout=1&retry_interval=15,tcp://198.51.100.2:11211?persistent=1&weight=1&timeout=1&retry_interval=15"
session.name = "myUploadProgressSession"
It's not possible to specify these settings via ini_set("session.save_handler", "memcache") in code, since this is executed too late.
