Usage of Thinkphp cache function Use the shortcut cache function S() in thinkphp for caching, for example:

//This class is automatically generated by the system and is for testing purposes only
 class IndexAction extends Action{
 public function index(){
 //If there is a cache, read the cache data
 //If there is no cache, read the data from the database and put it into the cache
 $lists=S('lists');
 if(emptyempty($lists)){
 $news=M('news');
 $ lists=$news->select();
 S('lists',$lists,600);
 echo 'This is data directly read from the database';
 }
 dump($list);
?>

Visit http://127.0.0.1/Home/index.php/Index/index Output Read data from the database directly:

array(10) {
 [0] => array(12) {
 ["id"] => string(1) "1"
 ["catid"] => string( 2) "13"
 ["title"] => string(4) "thinkphp's caching technology"
 ["content"] => string(8) "thinkphp's caching technology"
 ["tags"] = > string(4) "caching"
 ["thumb"] => string(0) ""
 ["description"] => string(7) "thinkphp's caching technology"
 ["inputtime"] = > string(10) "1348370202"
 ["posid"] => string(1) "1"
 ["ord"] => string(1) "2"
 ["hits"] => string(1) "1"
 ["status"] => string(1) "1"
}
