Basics

The memcache sonsists of 2 parts: the server MemCached and the client MemCache.

• MemCached is the cache server, the same as Mysqld (mysql server), which save and feed cache to clients.
• MemCache is a client. With php, we need to install it as a mod, just the same as pdo_mysql (php_pdo_mysql.dll on windows).

Install MemCached

• Download memcached from http://code.jellycan.com/memcached/ (get the
  win32 binary version). Here we suppose you extract the memcached in d:\memcached\.
• If you are on Sindows Vista/7, rightclick on memcached.exe and select Properties; click on the Compatibility tab. At the bottom you’ll see Privilege Level, check “Run this program as an administrator”.
• Open the command line by Win + R (or Start -> All Programs -> Accessories -> Command Prompt), and then run: d:\memcached\memcached.exe
-d install to install the service.
• Still in the command line, run d:\memcached\memcached.exe -d start, or net
start "memcached Server" to start the service.
• Check whether the service is running. Open Windows Task Manager, go to Services tab, you should find status of “memcached server” is “Running”.

Install MemCache php module

• Download memcache. Win 32 bit version: http://downloads.php.net/pierre/ and
  64 bit version:http://www.anindya.com/php-5-3-3-x64-64-bit-for-windows/ (choose
  Memcache 2.2.6 VC9 x64 Thread Safe).
• Extract memcache to you WAMP php ext folder, for example: D:\wamp\bin\php\php5.3.4\ext.
• Edit your php.ini file by adding: extension=php_memcache.dll.
• Restart apache server.
• Check php_info(); and you will find a module “memcache”.

Note

• To change MemCached memory size (default is 64mb), go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\memcached Server in your registry, find the ImagePath entry and change it to:
  “C:\memcached\memcached.exe” -d runservice -m 512
