reids与fastcgi_finish_request使用示例

伪代码：

<?php

$watchKey = $redis->get("watchKey");
$total = 100;   //数量
if($watchKey < $total){
    $redis->watch("watchKey");
    $redis->multi();

    //插入数据
    $redis->hSet("watchList","user_id_".$user_id_, $data);
    $redis->set("watchKey",$watchKey++);
    $result = $redis->exec();
    if($result){
        echo "抢购成功！<br/>";
        if(function_exists("fastcgi_finish_request")){
            fastcgi_finish_request();
            processData($data);
        }else{
            $watchList = $redis->hGetAll("watchList");
            //Async Processing;
        }
    }else{
        echo "手气不好";
        die;
    }
}
?>
