The PHP framework I am building (MindaPHP) already contains support for MySQL and cURL. Today I have added Memcache support. Memcache can be used for two main purposes in PHP: session storage and application caching. In the framework we only support debugging Memcache for application caching. This is how the debugger looks when the Cache class is used:
The cache is used to store the results from the Bing query. You can try this on: http://maurits.server.nlware.com/hello/bing (click the debugger link in the bottom bar after searching).
Memcache for application caching
Now you can speed up your application using the following commands:
$var = Cache::get($key) $success = Cache::set($key,$var,$expire=0) $success = Cache::delete($key) $success = Cache::add($key,$var,$expire=0) $success = Cache::replace($key,$var,$expire=0) $var = Cache::increment($key,$value=1) $var = Cache::decrement($key,$value=1)
The commands “get” and “set” do retrieval and storage of values in the cache based on the “key” parameter. The commands “add” and “replace” are comparable to “set”, but either fail when the key does (in case of add) or does not (in case of replace) exist. The “increment” and “decrement” commands can be used for counters, but beware that “increment” fails when the key does not exist. This is why you may want to call “add” before you increment.
Memcache for session storage
If you want to use Memcache for session storage in PHP (with any framework), you configured this in “php.ini” with the following statements:
session.save_handler = memcache session.save_path = "tcp://localhost:11211"
Note that you need the Memcache daemon and the php Memcache extension installed. The following command installs the required software on a Debian based Linux (like Ubuntu):
sudo apt-get install php5-memcache memcached
Have fun accelerating you application!
