README
Elephant - a highly performant PHP Cache Driver for Kirby

Usage
Cache methods
$cache = \Bnomei\PHPCache::singleton(); // or $cache = elephant(); $cache->set('key', 'value', $expireInMinutes); $value = elephant()->get('key', $default); elephant()->remove('key'); elephant()->flush();
Cache file(s)
All data is written at the end of the php script life-cycle. This does not count against your script execution time but for example when you change value in the cache with each request writing that big file everytime the time might prove inefficient. Further more incremental updates will be written during script execution depending on the mono_dump
setting. Additions to the cache will also be each written in temporary files to improve stability of the cache.
Serialization of data
This plugin defaults to a simple serialization logic which is quick but only serializes primitive data types, closures, objects that have a toArray()
-method like Kirby\Cms\Field
and Kirby\Toolkit\Obj
. This should be enough for most usecases.
If you need broader support set bnomei.php-cachedriver.serialize
to json
which will en- and decode your data as json before storing it. That is a bit slower but will ensure your data contains only primitive types without the hassle of serializing it manually before caching it.
OPCache
Make sure OPCache is configured to load the php files from the cache without any delay. Most probably you will have to set these values in your user.ini
or something similar! If you do not set these values you might have outdated data being loaded from php files cached by OPCache instead of loading the right ones you want from disk.
opcache.enable=1 opcache.enable_cli=0 # default is 0, leave it like that opcache.validate_timestamps=1 opcache.revalidate_freq=0 # default is 2, 0 => on every request
Thanks Al for helping me get these config values right.
Benchmark
elephant()->benchmark(1000);
php : 0.03383207321167 file : 2.3811981678009
ATTENTION: This will create and remove a lot of cache files and php-cache files
No cache when debugging
When Kirbys global debug config is set to true
the complete plugin cache will be flushed and no caches will be read. But entries will be created. This will make you live easier – trust me.
How to use Elephant with Lapse or Boost
You need to set the cache driver for the lapse plugin to php
. Please be aware that the mono-mode is not suited for concurrent writes.
site/config/config.php
<?php return [ 'bnomei.lapse.cache' => ['type' => 'php'], 'bnomei.boost.cache' => ['type' => 'php'], //... other options ];
Setup Content-File Cache
Use Kirby 3 Boost to setup a cache for content files.
