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";
}
}
}
?>
以上就是yii框架redis+php实现秒杀效果的实例分析的详细内容。
