                            var_dump($db->connect_error);
                            exit;

                   $sql = 'select * from test';
                   $db->query($sql,function($db,$result){
              	     if($result ===false){
                              echo 'query false';
                	 }elseif($result ===true){
                              echo 'query ok';
                  	 }else{
                              print_r($result);
                  	 }
                   $db->close();
              });
           });
	return true;

	}

}


$my = new AsyncMysql();

$res = $my->execute(1,1);
var_dump($res);
echo 'this is ok?';

运行结果：

这bool(true)
this is ok?mysql Connect

小总结：异步操作数据库内容会在最后被执行，可以运用到页面记录、用户登录更新等操作。
异步执行操作数据记录，既不影响用户的访问速度，又把统计给做了，岂不是美滋滋！
