A minimalistic cache adapter interface that was part of the Semantic MediaWiki code base and is now being deployed as independent library.

  • Support for MediaWiki's BagOStuff cache interface
  • Support for the Doctrine cache interface
  • Support for the Zend cache (ZF2) interface
  • Provides a FixedInMemoryLruCache array LRU cache without any external cache provider dependency
  • Provides a CompositeCache to combine different cache instances and allow access through hierarchical iteration on a first-come first-served basis


PHP 5.3 / HHVM 3.3 or later


The recommended installation method for this library is by either adding the dependency to your composer.json.

```json { "require": { "onoi/cache": "~1.1" } } ```


```php class Foo {

private $cache = null;

public function __constructor( Onoi\Cache\Cache $cache ) {
    $this->cache = $cache;

public function doSomething( $id ) {

    if ( $this->cache->contains( $id ) ) {
        // do something

} php $cacheFactory = new CacheFactory();

$instance = new Foo( $cacheFactory->newFixedInMemoryLruCache( 500 ) ); $instance->doSomething( 'bar' );

$compositeCache = $cacheFactory->newCompositeCache( array( $cacheFactory->newFixedInMemoryLruCache( 500 ), $cacheFactory->newMediaWikiCache( new () ), $cacheFactory->newDoctrineCache( new ( '/C/Foo' ) ) ) );

$instance = new Foo( $compositeCache ); $instance->doSomething( 'bar' ); ```
