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";

}

}

}

?>
