PHP Cache Interface

Cache

This script works as simple interface with APC, Memcache, Memcached and Files to store data into cache.

You will can store different data into different cache methods (some examples into settings-example.php).

Examples

Files cache

<?php
include (__DIR__.'/libs/ANS/Cache/Cache.php');
include (__DIR__.'/settings-example.php');

$Cache = new \ANS\Cache\Cache($settings['js']);

if ($Cache->exists('js-files')) {
    $content = $Cache->get('js-files');
} else {
    $content =  file_get_contents('https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js');
    $content .= file_get_contents('http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js');
    $content .= file_get_contents('http://modernizr.com/i/js/modernizr.com-custom-1.6.js');

    if ($custom_time) {
        $Cache->set('js-files', $content, $custom_time);
    } else {
        $Cache->set('js-files', $content);
    }
}

Database Query cache (into APC)

<?php
include (__DIR__.'/libs/ANS/Cache/Cache.php');
include (__DIR__.'/settings-example.php');

$Cache = new \ANS\Cache\Cache($settings['db']);

$query = 'SELECT * FROM Users;';
$cache_key = md5($query);

if ($Cache->exists($cache_key)) {
    $rows = $Cache->get($cache_key);
} else {
    $rows = mysql_fetch_assoc(mysql_query($query));

    if ($custom_time) {
        $Cache->set($cache_key, $rows, $custom_time);
    } else {
        $Cache->set($cache_key, $rows);
    }
}

Configuration cache (into Memcache)

<?php
include (__DIR__.'/libs/ANS/Cache/Cache.php');
include (__DIR__.'/settings-example.php');

$Cache = new \ANS\Cache\Cache($settings['config']);

$config_files = array(
    'db', 'paths', 'events', 'routes', 'templates', 'mail',
    'session', 'tables', 'actions', 'css', 'languages'
);

$config_key = md5(serialize($config_files));

if ($Cache->exists($cache_key)) {
    $configuration = $Cache->get($cache_key);
} else {
    $configuration = array();

    foreach ($config_files as $file) {
        if (is_file(__DIR__.'/config/'.$file.'.php')) {
            $configuration = array_replace_recursive($configuration, include(__DIR__.'/config/'.$file.'.php'));
        }
    }

    if ($custom_time) {
        $Cache->set($cache_key, $configuration, $custom_time);
    } else {
        $Cache->set($cache_key, $configuration);
    }
}
