First off, all credits go to this guy. I’m just listing the steps on how I did it in Windows 7 with PHP 5.3. Also, I tested this using WampServer but I believe it should work on any PHP install.

Install memcached

• Download the Memcached Win32 library here: http://code.jellycan.com/memcached/. Extract the downloaded archive file in a directory (e.g. c:\memcached). There should be a memcached.exe in there.
• Run a command prompt as an administrator. Some info on how to do that here.

• Install memcached as a service. Go to the memcached directory, type and run:

  memcached -d install
  

• Start the memcached service by running:

  memcached -d start
  

Install PHP Memcache extension (php_memcache.dll)

• Chances are you don’t have php_memcache.dll in your PHP extensions yet. You can download a build of it here. Make sure to download the correct one for your system. Mine was 32bit and PHP 5.3 so I used this: php_memcache-cvs-20090703-5.3-VC6-x86.zip. The archive should contain php_memcache.dll. Extract the archive to your php extensions directory. On my system (WampServer), this was C:\wamp\bin\php\php5.3.0\ext.

• Edit php.ini, add this line to enable the extension:

  extension=php_memcache.dll
  

  This is a little easier for WampServer users because there’s a menu for enabling extensions ^_^x

Test

Test the installation using the sample PHP code here: http://www.php.net/manual/en/memcache.examples-overview.php.
