Updated: APC download using latest code (3.0.12p2).

Please find following the compiled binaries of APC for Windows using Microsoft VC++ 6. For PHP 4 versions see: PHP APC binaries for PHP 4.x.
If you need a version not offered here, let us know (post comment).

APC windows binaries follow the naming conversion: php_apc_VVV_PHPVERSION.dll with:
VVV: the version of APC
PHPVERSION: the version of the targeted PHP

Example php_apc_3012p2_php516.dll is built from APC version 3.0.12p2 targeting the php version 5.1.6.
You can rename your download following the "standard" name: php_apc.dll

Help with installing and configuring APC.

File details, when applicable:
VERSION_Useful_Files.zip contains the readme and the php control panel.

Following you can download the PHP APC binaries for your version of PHP 5.
Please post any positive or negative experience you have using these downloads. Avoid posting bugs related to APC (binary bugs will most likely appear immediately: when loading or first use). Post only issues relating to the apc downloads or requests. Please do not post support issues about APC under this article. You can do so in the PHP Section of the Forums.

What is the deal with PATH_MAX  ?
When compiling APC I receive the message that PATH_MAX is undefined. So I had to set a value.
After a little research it looks like this value is related to the length of paths. Some character encoding might using 2 bytes per character, so we compiled a version with PATH_MAX = 512.
Update: Although the 512 version works fine, it has be suggested that 2048 might be a better value (thanks Steffen!).
