Installation

composer require wshafer/psr11-phpcache

Usage

<?php

// Get a pool
$pool = $container->get('myCacheServiceName');

// Get an item (existing or new)
$item = $pool->getItem('cache_key');

// Set some values and store
$item->set('value');
$item->expiresAfter(60);
$pool->save($item);

// Verify existence
$pool->hasItem('cache_key'); // True
$item->isHit(); // True

// Get stored values
$myValue = $item->get();
echo $myValue; // "value"

// Delete
$pool->deleteItem('cache_key');
$pool->hasItem('cache_key'); // False

Containers

Any PSR-11 container wil work. In order to do that you will need to add configuration and register the factory \WShafer\PSR11PhpCache\PhpCacheFactory()

Below are some specific container examples to get you started

Pimple Example

// Create Container
$container = new \Xtreamwayz\Pimple\Container([
    // Cache using the default keys.
    'cache' => new \WShafer\PSR11PhpCache\PhpCacheFactory(),
    
    // Another Cache using a different cache configuration
    'otherCache' => function($c) {
        return \WShafer\PSR11PhpCache\PhpCacheFactory::cacheTwo($c);
    },

    'config' => [
        'caches' => [
            /*
             * At the bare minimum you must include a default cache config.
             * Otherwise a void cache will be used and operations will be 
             * be sent to the void.
             */
            'default' => [
                'type'      => 'void',         // Required : Type of adapter
                'namespace' => 'my-namespace', // Optional : Namespace
                'prefix'    => 'prefix_',      // Optional : Prefix.  If a Namespace is configured and the adapter supports it, the Namespace will me used instead.
                'logger'    => 'my-logger',    // Optional : PSR-1 Logger Service Name
                'options'   => [],             // Optional : Adapter Specific Options
            ],
            
            // Another Cache
            'cacheTwo' => [
                'type'      => 'memcached',    // Required : Type of adapter
                'namespace' => 'my-namespace', // Optional : Namespace
                'prefix'    => 'prefix_',      // Optional : Prefix.  If a Namespace is configured and the adapter supports it, the Namespace will me used instead.

                    'skipOnFailure' => false,                   // Optional : If true we will remove a pool form the chain if it fails. (Default: false)

Frameworks

Any framework that use a PSR-11 should work fine. Below are some specific framework examples to get you started

Zend Expressive

You'll need to add configuration and register the services you'd like to use. There are number of ways to do that but the recommended way is to create a new config file config/autoload/cache.global.php

Module Config

If you're not using the Zend Component Installer you will also need to register the Module.

config/modules.config.php (ZF 3 skeleton)

<?php

return [
    // ... Previously registered modules here
    'WShafer\\PSR11PhpCache',
];

config/application.config.php (ZF 2 skeleton)

<?php

return [
    'modules' => [

$container['otherCache'] = function($c) {
    return WShafer\PSR11PhpCache\PhpCacheFactory::cacheTwo($c);
};

Configuration

• Named Services : These are services names wired up to a factory. The configuration will differ based on the type of container / framework in use.

• Adapters : Cache Pool config tell us what type of cache to use and how to connect to that cache. Some caches provide other special options on how to handle the data and what data to handle. See the appropriate apdaptor config below.

Minimal Configuration

A minimal configuration would consist of at least one default cache and one named service. Please note that if you don't specify a default cache a Void pool will be used when you wire up the default cache.

Minimal Example (using Zend Expressive for the example)

<?php

return [
    'dependencies' => [
       'factories' => [
           // Cache using the default keys.
           'cache' => \WShafer\PSR11PhpCache\PhpCacheFactory::class,
       ]
    ],
    
    'caches' => [
        /*
         * At the bare minimum you must include a default cache config.
         * Otherwise a void cache will be used and operations will be 
         * be sent to the void.
         */
