2. 操作实例

require_once&#39;memcache2.php&#39;; 
$getData = new cache_memcache (); 
$res = $getData->get("Shibly"); 
if ($res) { 
    echo $res; 
} else { 
    echo "No data to display. The cache may be destroyed"; 
}
 
 
 
$srv_stat = new cache_memcache(); 
$srv_stat->ServerStatus();
 
 
require_once(&#39;memcache2.php&#39;); 
$setData = new cache_memcache(); 
$data =  $setData->save("Shibly","Hello there ! you&#39;ve stored me in a memcached server !"); 
 
if($data) 
{ 
    echo "You&#39;ve successfully stored data in the memcached server.
     Please Run the example_get_cache.php file to retrive your data";
} 
 
else{ 
    echo "There is something wrong with your caching server"; 
}
