Fatal error: Class 'Memcache' not found in Zend Framework + Wamp - php

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;
?>
