yii框架redis结合php实现秒杀效果(实例代码)

废话不多说了，直接给大家贴代码了，具体代码如下所示：

<?php
namespace backend\\controllers;
use Yii;
use yii\\web\\Controller;
/**
* 
*/
class GoodsController extends Controller
{
public $enableCsrfValidation=false;
public function actionInfo()
{
$data=yii::$app->db->createCommand(\"select * from goods \")->queryAll();
return $this->render(\'index\',[\'data\'=>$data]);
}
Public function actionXx()
{
$id=yii::$app->request->get(\'id\');
$data=yii::$app->db->createCommand(\"select * from goods where id=\'$id\'\")->queryOne();
return $this->render(\'info\',[\'data\'=>$data]);
}
Public function actionAdd()
{
$a=yii::$app->redis;
if (Yii::$app->request->isPost)
{
$data=yii::$app->request->post();
$res=yii::$app->db->createCommand()->insert(\'goods\',$data)->execute();
if($res)
{
for ($i=0; $i <$data[\'counts\'] ; $i++)
{ 
$a->lpush(\'goods\',1);
}
return $this->redirect(array(\'goods/info\'));
}
else
{
echo \"添加失败\";
}
}
else
{
return $this->render(\'add\');
}
}
public function actionOrder()
{
$redis=yii::$app->redis;
$count=$redis->lpop(\'goods\');
if(empty($count))
{
echo \"库存不足\";die;
}
$res=yii::$app->db->createCommand(\"update goods set counts=counts-1 where id=1 and counts>0\")->execute();
if($res)
{
echo \"秒杀成功\";
}
else
{
echo \"秒杀失败\";
}
}
}
?>
