How to implement the broadcast reminder function in PHP

php implements the broadcast reminder function: 1. Create a php sample file and obtain the anchor information from the database or API; 2. Use the "$redis = new Redis()" syntax for caching and save the anchor information Enter the local or server to facilitate query; 3.

php method to implement the broadcast reminder function:

1. Create a php sample file and obtain the anchor information

<?php
    
// 假设这是从数据库或 API 获取到的主播信息，其中包括主播 ID、主播名字和开播时间
    
$anchor_id = 123456;    
$anchor_name = "小明";    
$start_time = time() + 3600; // 开播时间为当前时间加上一个小时
?/>

2. Use "Redis "As a cache, store the anchor information locally for future query

// 将主播信息存入本地存储或数据库中，方便后面查询
    
// 这里假设使用了 Redis 作为缓存
    
$redis = new Redis();    
$redis->connect('127.0.0.1', 6379);    
$redis->set("anchor:$anchor_id:name", $anchor_name);    
$redis->set("anchor:$anchor_id:start_time", $start_time);

3. Use "RabbitMQ" as the message queue, add the broadcast reminder to the task queue, and wait to send the reminder message when the broadcast time is reached.

// 将开播提醒加入任务队列，等待到达开播时间时发送提醒消息
    
// 这里假设使用了 RabbitMQ 作为消息队列
    
$rabbitmq = new AMQPConnection(
array('host' => 'localhost',        'port' => '5672',        'login' => 'guest',        'password' => 'guest'
    ));    
$rabbitmq->connect();    
$channel = new AMQPChannel($rabbitmq);    
$exchange = new AMQPExchange($channel); 
    
$exchange->setName('remind');    
$exchange->setType(AMQP_EX_TYPE_DIRECT);    
$exchange->declareExchange();    
$message = json_encode(array('anchor_id' => $anchor_id));    
$exchange->publish($message, 'remind');    
echo "开播提醒已设置！";
