Checking Memcached is working correctly

This guide explains how to know whether Memcached is working properly on your hosting. 

Prerequisites

• Install Memcached on your managed Cloud server

Checking Memcached is running

1. Copy the following code in a PHP file:

// login to the local memcache server
$fp = fsockopen("localhost", 11211);
if ($fp) {
// we are asking for the stats
fwrite($fp, "statsn");
while (!feof($fp)) {
$buf = rtrim(fgets($fp));
if (preg_match('/^STAT curr_items ([0-9]+)$/', $buf, $matches)) {
// the number of items stored
print $matches[1] . PHP_EOL;
} elseif (preg_match('/(END|ERROR)/', $buf)) {
// end of the stats
break;
}
}
fclose($fp);
} else {
print "Error: cannot connect to local memcached server: $!" . PHP_EOL;
}

2. Download the PHP file to your hosting.

3. Run the PHP file. The script sends the number of elements cached in the server memory.
