How to check if memcache or memcached is installed for PHP?

Question

How do I test if memcache or memcached (for PHP) is installed on my Apache webserver?

Memcache is a caching daemon designed especiall

Answer 1

this is my test function that I use to check Memcache on the server

connect('localhost', 11211) or die ("Could not connect");

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

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

    var_dump($get_result);
 }

if you see something like this

    Server's version: 1.4.5_4_gaa7839e
    Store data in the cache (data will expire in 10 seconds)
    Data from the cache:
    object(stdClass)#3 (2) { ["str_attr"]=> string(4) "test" ["int_attr"]=> int(123) }

it means that everything is okay

Cheers!
