PHP uses memcached cache to add, delete, modify and query data

//Create a memcache object instance
$memcache = new Memcache;
if(!$memcache->connect("127.0.0.1",11211)){
 die('Connect Failed');
}
if($memcache->set('key1',"xian",MEMCACHE_COMPRESSED,60)){
 echo 'sucess!';
}//Save the value, where the xian string is also Can be an array, object, but not a resource
// bbs.it-home.org
$val = $memcache->get('key1');//Query to get the value
echo $val;
$memcache- >replace('key1','beijing',MEMCACHE_COMPRESSED,60);//Modify
$memcache->delete('key1');//Delete
?>
