I keep getting the fuel error that my php doesn't have memcached extention loaded. Fuel\Core\Fuel_Exception [ Error ]: Memcached cache are configured, but your PHP installation doesn't have the Memcached extension loaded. But if i echo phpinfo() I can clearly see the extention there. I can see the memcached process running on the server as well. In addition if I put something like

$memcache = new Memcache;
$memcache->connect('127.0.0.1', 11211);
print_r($memcache);
exit;

on a page I'll get an output of Memcache Object ( [connection] => Resource id #3 ) which leads me to believe its not a php issue. Not sure if its relevant but shouldn't it be trying to load the memcache extension not memcached any thoughts on how to troubleshoot this?

As you have discovered, there are two implementations in PHP to acces memcached: the old one (memcache) and the new one (memcached). Fuel implements the new one, with is more feature rich, less buggy, but requires a PECL module to be installed on the server. old: http://php.net/manual/en/book.memcache.php
new: http://php.net/manual/en/book.memcached.php I have to admit there choice of naming could have been better...

Gotcha, I also figured out that centos 5.6, my os, removed the pecl and memcache packages which is why I was having so much trouble.

i have same problem with memcached
memcached and every things it needs are installed on my OS (ubuntu 10.04)
this command: [/etc/init.d/memcached start] says me [memcached is already running], but fuel says:
[Memcached cache are configured, but your PHP installation doesn't have the Memcached extension loaded.]
what is the problem?

here a sample code (form http://www.php.net) for test memcached:
$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); and here its result: Server's version: 1.4.2
Store data in the cache (data will expire in 10 seconds)
Data from the cache:
object(stdClass)#13 (2) { ["str_attr"]=> string(4) "test" ["int_attr"]=> int(123) }

hueman, what php version is running? I personally use dotdeb.org, but notices that after upgrading to 5.3.8 - my memcached stopped working and I get the same error

hueman

my PHP version: 5.3.2

I ended up just changing the fuel cache class to use memcache. The methods for Memcached and Memcache are pretty much identical so it was just a few lines to change. Not an ideal solution, but I don't want to install 3rd party php rpm's that might affect other packages.

// do we have the PHP memcached extension available
            if (!class_exists('Memcache')) {
                throw new \Fuel_Exception('Memcache cache are configured, but your PHP installation doesn\'t have the Memcache extension loaded.');
            }

            $memcache = new \Memcache;
            $memcache->addServer('127.0.0.1', 11211);
           
            $this->memcached = $memcache;
