How do you use memcached (not memcache) with PHP (part 2)

Question

On the first page, I have this

// start memcached
$m = new Memcached();
$m->addServer('localhost', 11211);
$key = 'test_' . $ID_ref;
$test_data = array(....);
$m->set($key, $test_data);
// end memcached

OK, so far. On the next page,

// start memcached
$m = new Memcached();
$m->connect('localhost', 11211);
var_dump($m->get($key));
// end memcached

The following error occured:

Call to undefined method Memcached::connect()

phpinfo() shows that memcached is installed by webhost, and it seems that memcached does not support connect()

What should I use instead?

Rather than

$m = new Memcached();
$m->connect('localhost', 11211);

simply re-use

$m = new Memcached();
$m->addServer('localhost', 11211);

connect() is a Memcache method and not Memcached

I got this output bool(false) What does it mean?

Just ensure your $key values are the same on both set() and get() calls. If you wish to test it's working OK you can perform a set and a get after each other in the same script.

they are the same, I've set both to $key = 'test_1'; for both with the same result

It is bool(false) also on the same script.

I'm not sure what else to help you with sorry, memcached really is a simple little beastie, you can try getting a memcache admin panel to check that you're successfully storing keys. eg code.google.com/p/phpmemcacheadmin
