PECL 4 Win has been down for quite a while making the search for some PHP extensions unnecessarily difficult. I’m offering this permanent APC download for not only my records, but to help others searching for it. As of August 19th, 2009, 3.1.3 is the latest beta version, and 3.0.19 is the latest stable.
Download php_apc (Windows 3.0.19 Stable)
Download php_apc (Windows 3.1.3 Beta)
