致命错误：在Zend Framework + Wamp中找不到类“ Memcache”

Question

I have following code :

in application.ini

cache.default.adapter = "memcached"
cache.default.params.host = "localhost"
cache.default.params.port = "11211"

in Bootstrap.php

$cache = new Memcache();        
$cache->connect($cache_params['host'], $cache_params['port']);
Zend_Registry::set("cache", $cache);

and also I am having memcache installed on my machine by putting php_memcache.dll in wamp\\bin\\php\\php5.3.9\\ext and also extension=php_memcache.dll in php.ini

But still I am getting the following error :

( ! ) Fatal error: Class 'Memcache' not found in \\wamp\\www\\projectname\\application\\Bootstrap.php on line 160

I have gone through google but still not able to solved the problem. What is the problem why it's not connecting to the memcache.

Answer 1

You are trying to cache your database?

You want to use Zend_Cache.

(From: http://zendcoding.com/how-to-use-memcached-in-the-zend-framework )

$frontendOpts = array(
    'caching' => true,
    'lifetime' => 1800, //how long in seconds to keep the cache for.
    'automatic_serialization' => true //In order to store objects and arrays, Zend must first serialize data into a string. If this parameter is set to ‘true‘, this serialization will happen on the fly and behind the scenes.
);

$backendOpts = array(
    'servers' =>array(
        array(
        'host'   => $cache_params['host'],
        'port'   => $cache_params['port'],
        'weight' => 1
        )
    ),
    'compression' => false
);

$cache = Zend_Cache::factory('Core', 'Memcached', $frontendOpts, $backendOpts);

This link also demonstrates how to load and update the cache, and how to make it accessible from everywhere in your application. A good read, to be sure.

Your setting is memcached

cache.default.adapter = "memcached"

but you want to use memcache

$cache = new Memcache();

Try this example

 <?php $mc = new Memcached('mc'); $mc->setOption(Memcached::OPT_LIBKETAMA_COMPATIBLE, true); if (!count($mc->getServerList())) { $mc->addServers(array( array('127.0.0.1',11211), array('127.0.0.1',11211), )); } $key = 'mykey'; $mc->add($key,'test for memcached not memcache'); $val = $mc->get($key); echo $val; ?>
