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";
}
}
}
?>
