How can I install APC on Windows? I am using PHP 5.3, Windows 7 x64.
I used
pecl install apc
I got
C:\\PHP>pecl in
Also, make sure that the compiled version from here http://downloads.php.net/pierre/ matches your php version, otherwise the extension will not load (php v. 5.2.17 requires php_apc.dll v 5.2.17.17 - which doesn't seem to be available as of this writing - I had to downgrade the php version to play with apc).
Another point, pierre's zip packages, at least the one I downloaded, did not include the management script. you can get it from here: http://pecl.php.net/package/APC - select the version you downloaded, then navigate to Browse Source, then find your version in the 'tags' folder. the apc.php script should be there.
