I am using wamp, PHP 5.4 running on win 8, I can't seem to get PHP to acknowledge the memcache dll. I download php_memcache-3.0.8-5.4-ts-vc9-x86.zip (the only one I could find). I copied the dll to C:\wamp\bin\php\php5.4.12\ext I added extension=php_memcache.dll restart the server. but still I cannot use memcache, and it is missing from Loaded Extensions list. Please supply a step-by-step instruction on how to set this up, Thanks.
