PHP 使用redis 實現定時任務

直接上代碼吧

配置文件中開啟鍵空間通知  notify-keyspace-events Ex

1.新建index.php

$redis = new \Redis();
//連接本地的 Redis 服務
$redis->connect("127.0.0.1", 6379);

$redis->setOption(\Redis::OPT_READ_TIMEOUT,-1);
echo "訂閱消息監聽 \n";
$redis->psubscribe(array('__keyevent@0__:expired'), 'psCallback');

function psCallback($redis, $pattern, $chan, $msg)
{
    echo "Pattern: $pattern\n";
    echo "Channel: $chan\n";
    echo "Msg: $msg\n";
}

執行php index.php

2.新建文件index2.php

$redis = new \Redis();
//連接本地的 Redis 服務
$redis->connect("127.0.0.1", 6379);
$redis->set("name", "test");
$redis->expire("name", 3);

3.3秒后輸出
