This guide explains how to manage Memcached and, in particular, how to check if this in-memory caching system is working correctly on your Managed Cloud Server.

Prerequisites

• Install Memcached on Managed Cloud Server.

Check Memcached execution

To verify that Memcached is working correctly:

1. Copy the following code into a PHP file:

   						// connexion au serveur memcache local		
   $fp = fsockopen("localhost", 11211);
   if ($fp) {
   // on demande les stats
   fwrite($fp, "stats\n");
   while (!feof($fp)) {
   $buf = rtrim(fgets($fp));
   if (preg_match('/^STAT curr_items ([0-9]+)$/', $buf, $matches)) {
   // le nombre d'items stockes
   print $matches[1] . PHP_EOL;
   } elseif (preg_match('/(END|ERROR)/', $buf)) {
   // fin des stats
   break;
   }
   }
   fclose($fp);
   } else {
   print "Error: cannot connect to local memcached server: $!" . PHP_EOL;
   }

2. Upload the PHP file to your hosting.
3. Run the PHP file.

The script returns the number of elements cached in the server's memory.
