> You guys realize that the stat cache is per-request
nonsense - it's per prcoess and "You only need to clear the stat cache before a
file_exists() call" is bullshit, you should be able to clear it *after* change a file but you
just paly lotterly for which request in the future clearstatcache() has any effect or was just a
joke
https://bugs.php.net/bug.php?id=73888 is a
deisgn error wihich makes a) the cache mostly usesless and b) clearstatcache() to a lottery game

We really need this option to disable cache in daemons, written in PHP.
WebSocket server for example. Or some worker, which listens the queue and performs some jobs.

Okay, the stat cache was not to blame for this problem I commented on above as I just learned it
doesn't cache negative results but I still need a way to disable it. I could get problems in
the future when file_exists returns true for a file that does not exist anymore.

I'm writing a PHP CLI daemon and the stat cache just burned me hard because it made
file_exists() incorrectly return false for a file that had been created by another program. There
NEEDS to be a way to disable this. My only option now appears to be to write my own file system
wrapper functions to bypass this annoying behavior.

You guys realize that the stat cache is per-request, right? You only need to
clear the stat cache before a file_exists() call if you A. did a stat for it, and
B. either created or deleted it on that request. In which case you shouldn't need
to stat it again since the success status of the create/delete will tell you
whether the file is there or not. Perhaps for long-running daemons or something
this becomes more of an issue, but for a typical web request the stat cache
typically saves you dozens of system calls.

when this will be fixed?
when lot of users work on same files is needed to clear the cache on every call to stat functions:
this is totally annoying
in plus clearing the cache every time is slower against not cache at all
please fix :)
thank you
