I don't really care either way, but if it's a well known fact, might as
well stop trying. Does APC work on Windows? I recently submitted a patch
to fix the snaps.php.net compilation of APC, but for any non-trivial
script (interestingly enough, apc.php and and phpinfo() work fine), APC
segfaults or otherwise fatally errors. Some errors I've seen include:
[apc-error] Cannot redeclare class simpletest, referer: http://localhost/
on code that works perfectly without APC. I've scanned the bug list and
there are quite a few reports of APC not working on Windows--so, is this
generally known to be the case?

I'm running php 5.2.5 NTS with APC 3.1.0-dev. It works, but not without some
issues, like occasionally get a FastCGI process crashing which I suspect is
APC.
More worringly, have a tiny application which consistantly executes the
wrong page, when APC is enabled.
The index.php opens a frameset, with the left frame requesting browser.php,
but instead the output of index.php is sent.
Disable APC and the problem goes away.
Haven't been enable to write a failing test case to report it.

Hello Jared,
Doesn't running APC under FastCGI kind of defeat the purpose of APC?

No, why should it? The cache is shared perfectly fine if you let PHP
handle the process spawning (i.e. increasing PHP_FCGI_CHILDREN instead
of running php-cgi -b (or whatever) multiple times).
I used APC w/ FastCGI some time ago and I'm still using another opcode
cache with FastCGI at the moment (XCache), and I know lots of people
doing the same. :)

you're right, but too bad there's no PHP_FCGI_CHILDREN (pre-fork) for
windows, not even any alternatives
{{{
#ifndef PHP_WIN32
/* Pre-fork, if required */
if (getenv("PHP_FCGI_CHILDREN")) {
children = atoi(getenv("PHP_FCGI_CHILDREN"));
}}}

As phpxcache mentioned, that's not an option in Windows. Are you running
Windows or Linux? I'm sure APC works on Linux; I'm curious about Windows.

Sorry, I'm running Linux and did not think of a reason why
PHP_FCGI_CHILDREN would not be supported on windows, especially since
the "normal" way of doing FastCGI doesn't work on Windows at all (as fd
!= socket in Windows).
So, mOo is right of course. :)

We don't have any active developers contributing to APC on Windows at
the moment. We try to not do stuff that will break Windows, but beyond
that we rely on people interested in that platform to step up and help out.

I wish I could say, "Yes! I'm interested in helping out!" but I don't
know enough about this area to really do anything useful except complain
that things aren't working. When I get a chance, I'm going to try to set
up APC on a clean Windows Vista install with the pre-compiled binaries.
If it still fails, I give up and figure out how to install APC on Ubuntu.

Use XCache instead - it's simple, fast and stable. APC is far more complex
and unstable (is't like code for code)

I wouldn't dare host a production website on a Windows website ;-). I'm
much more interested in getting APC running for testing purposes; seeing
how nicely my code plays with the opcode cache, whether or not a
different include scheme would result in better performance, etc.
Testing with XCache would be helpful (and I will certainly look into
it), but APC is the industry standard and my first priority.

There is no difference whatever it's APC or XCache - they do the same and
their speed's are identical, XCache is little faster but thouse are below
0.5-1 % differences. So i purpose you try XCache on Windows and see if it's
working fine. At least I haven't seen any complaints on XCache forum that it
doesn't work under Windows. And Xcache has admin page with all stats you
need to see what is happening inside it. It's site is

xcache does not reduce peak memory usage. APC and Zend Accelerator do.

I've never found APC to be unstable. And I imagine that neither Yahoo or
facebook have issues with this. You might just be seeing a bug in an
extension that just gets more prone to show up when APC is activated.
On top of that, as we've no idea who actually develops Xcache -- I just
see "phpxcache" -- I wouldn't want to put this on any sort of production
machine either. I simply can't trust an alias of one person over a group
of people that have shown to know a helluvalot about PHP's internals.

I have run APC on my windows PC for years (development machine), through many different php versions. I have found APC to be unstable when loaded with debugging libraries (espec zend debugger). Other than that, it is stable as.
If you are having troubles, maybe check to see if you have any debugging dlls loaded.

The main problem here is to propose to use xyz when one is asking
support for APC. It is like saying to use Python/Ruby/Java to anyone
posting a bug or a question here, pointless.

Xcache is developed by mOo - one of the Lighttpd developers, so he can be
found on Lighttpd forum (they have XCache section), mailing list and IRC. I
have no trouble reaching lighttpd and xcache developers on IRC and they
helped me a lot, bugs I found were confirmed, fixed and deployed to SVN less
than in a hour - you just never used it and you don't know this software.
That doesn't mean it's bad or unstable. People are confirming it's stability
all the time.
Some my colleagues had bad luck with APC, so I just use what works for me
fine.
