Installation

hum... as usual...

put the code in vendors/Kitpages/SimpleCacheBundle

add vendors/ in the app/autoload.php

add the new Bundle in app/appKernel.php

You need to create a table in the database :

CREATE TABLE `simple_cache_backend` (
  `id` varchar(255) NOT NULL,
  `data` longtext COMMENT '(DC2Type:array)',
  `created_at` datetime NOT NULL,
  `updated_at` datetime NOT NULL,
  `expired_at` datetime default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

(or you can use php app/console doctrine:schema:update)

Users Guide

1/ record & retrieve into/from the cache

$cacheManager = $this->get('kitpages.simple_cache');
$html = $cacheManager->get(
    'my-cache-uniq-id-12',
    function() {
        $output = "hello world";
        sleep (3);
        return $output;
    }
);

2/ clear the cache

$cacheManager = $this->get('kitpages.simple_cache');
$cacheManager->clear('my-cache-uniq-id-12');

3/ a more complex example : arguments given to the callback and expiration

$html = $cacheManager->get(
    'my-cache-uniq-id-12',
    function($arg1, $arg2) {
        $output = "hello world";
        sleep (3);
        return $output;
    },
    array(12, 34),
    $myExpirationTimeInSeconds
);

4/ multiple delete in the cache

$cacheManager = $this->get('kitpages.simple_cache');
$cacheManager->clear('my-cache-%');
// remove all the entries in the cache beginning by "my-cache-"
