## Basic usage

### memcache extension overview example

In this example, an object is being saved in the cache and then retrieved back. Object and other non-scalar types are serialized before saving, so it's impossible to store resources (i.e. connection identifiers and others) in the cache.

    <?php

    $memcache = new Memcache;
    $memcache->connect('localhost', 11211) or die ("Could not connect");

    $version = $memcache->getVersion();
    echo "Server's version: ".$version."<br/>\n";

    $tmp_object = new stdClass;
    $tmp_object->str_attr = 'test';
    $tmp_object->int_attr = 123;

    $memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");
    echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";

    $get_result = $memcache->get('key');
    echo "Data from the cache:<br/>\n";

    var_dump($get_result);

    ?>

### Using memcache session handler

    <?php

    $session_save_path = "tcp://$host:$port?persistent=1&weight=2&timeout=2&retry_interval=10,  ,tcp://$host:$port  ";
    ini_set('session.save_handler', 'memcache');
    ini_set('session.save_path', $session_save_path);

    ?>
