Enable memcache in WAMP

Download memcache for windows (DLL) from https://pecl.php.net/package/memcache

Extract the files (php_memcache.dll & php_memcache.pdb) and put in <drive>\wamp\bin\php\phpx.x.xx\ext

Update php.ini file with extension=php_memcache.dll (run test page with phpinfo and check “Loaded Configuration File” for php.ini configuration file )

Run following script to test memcache

$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);

Output:

 Data from the cache:
