To avoid this, do instead: This function will attempt to fetch an item from the cache store. We can easily abstract that into the following base class. I think we can achieve this if we store TTL out of the data in some way I could track it with the getmypid function, which returned a different value upon every request, but only from a limited set. The following example will load the cache driver, specify APC as the driver to use, and fall back to file-based caching if APC is not available in the hosting environment.

You need to handle the case where the file didn’t exist with some logic in your code with appropriate locking.

On Ubuntu, and on other debian based linuxes, you can install APC by typing sudo apt-get install php-apc on the command line. Doing this would save my three users milliseconds per year ; that’s why I’ve spent more than 10 hours on this: For more information on Memcached, please see http: The next problem qpc a little bit more complex. For more information on Memcached, please see http: Personally I prefer PDO or another abstraction library.

Caching Driver — CodeIgniter documentation

I have to codeigbiter that I haven’t checked it anymore since they fixed ‘my’ bug. You’ll only get a status update every few requests. Installing codeigniiter running APC cache with CodeIgniter February 13, 3 Minute Read Codeigniter 2 now includes an excellent cache driver, which makes it dead easy to use any one of the great available cache librairies such as APC o memcached. After installation, you need the Pecl extension. A good reason to prefix all your classes, is that they will never collide with other classnames if you need to include other code.


Caching in PHP using the filesystem, APC and Memcached

It seems the 0 default setting will not work on some ap. This function will save an item to the cache store. Memory-based caching might be the solution.

What about making two files: In codeigniter, you don’t need to do anything special. If a server has double the memory available for memcached, coeeigniter can double the weight. It is amazing in web development Sign up using Email and Password.

Caching in PHP using the filesystem, APC and Memcached

codeignitsr Have you tried any of these caching libraries with codeigniter 2? Multiple Memcached servers can be specified in the memcached. TTL should always be 10secs from the last accessed time.

It’s a simple table with good indexing and I haven’t yet experienced any slow behavior. Now, the only thing you have to do in order to use this class, is add servers.

The goal is to save a large set of constants to the cache. The information returned and the structure of the data is dependent on which adapter is being used. I don’t see any situation when you really have to cache data larger than 1MB. Your keys have to codeignietr unique system wide; it is therefore a good idea to namespace your keys.


They are 2 different APC caches. For low concurency 2 the improvement when using APC is similar: All the data is identified by a key. Before, it wouldn’t write to the file if it didn’t exist already. Flock operates on an open file handle opened by fopen codeigniher either locks a file for reading shared lock, everybody can read the file or writing exclusive lock, everybody waits till the writing is done and the lock is released.

Anyone who has enabled apc. I hope I explained things well.
