Durpal cache

It's more easy to use the drupal's cache than PHPCache, as we don't need to configure database again. However, more codes we need to write.

Example Code:

$result = cache_get($cid);

if($result!=null){

if(isset($result->data)&&isset($result->created)&&isset($result->expire))

{

$now = time();

//check time out

if($now<$result->expire)

{

$data = $result->data;

}

}

}

if($data==null){

$data = "your slow code result";

cache_set($cid,$data,"cache",time()+60*15);// time limit is 15min.

}
