PSR-16 is a simple caching library that uses the Simple Cache interface.

Requirements

• PHP 5.6 or higher
• PSR-16 Simple Cache Interface

Depending on the handler you will use, it may need PHP extensions.

• Redis
• PDO
• Wincache
• Memcache or Memcached

Installation

composer require initphp/cache

Usage

require_once "../vendor/autoload.php";
use \InitPHP\Cache\Cache;

$cache = Cache::create(\InitPHP\Cache\Handler\File::class, [
    'path'      => __DIR__ . '/Cache/';
]);

if(($posts = $cache->get('posts', null)) === null){
    $posts = [
        ['id' => '12', 'title' => 'Post 12 Title', 'content' => 'Post 12 Content'],
        ['id' => '15', 'title' => 'Post 15 Title', 'content' => 'Post 15 Content'],
        ['id' => '18', 'title' => 'Post 18 Title', 'content' => 'Post 18 Content']
    ];
    $cache->set('posts', $posts, 120);
}

echo '<pre>'; print_r($posts) echo '</pre>';

$options = [
    'prefix'    => 'cache_',
    'host'          => '127.0.0.1',
    'port'          => 11211,
    'weight'        => 1,
