How to use PHP to implement broadcasting reminder function

With the rise of the live broadcast industry, many people are flocking to this field. The broadcast reminder function can make it easier for your viewers to find your live broadcast, thereby increasing the viewing rate of the live broadcast room. This article will introduce you how to use PHP to implement the broadcast reminder function.

1. Early preparation

1.1 Configure the server

The broadcast reminder function needs to be implemented on the server. First, you need to configure a cloud server and install a PHP environment.

1.2 Prepare the data table

Create a new data table in the MySQL database to store information related to the broadcast reminder. The data table needs to contain at least the following fields:

• user_id: user ID, used to associate user information.
• anchor_id: anchor ID, used to associate anchor information.
• remind_time: The set reminder time.
• is_reminded: Whether it has been reminded, 0 means not reminded, 1 means reminded.

2. Implement the broadcast reminder function

2.1 The main implementation process of the broadcast reminder function

The main implementation process of the broadcast reminder function is as follows:

• The user clicks the "Start Reminder" button in the live broadcast room.
• After clicking the button, a pop-up box prompts the user to set the reminder time.
• After the user sets the reminder time, the background inserts the reminder information into the data table of the database.
• When the anchor starts live broadcast, the system will regularly scan the data table to see if there are records that need to be reminded.
• If there are records that need to be reminded, the system will remind the user through message push, email, etc.

2.2 Front-end code

<script type="text/javascript">
    function remind(anchor_id){
        var remind_time = //获取用户设置的提醒时间
        $.ajax({
            type: "POST",
            url: "remind.php",
            data: {
                anchor_id: anchor_id,
                remind_time: remind_time
            },
            success: function(result){
                if(result == "success"){
                    alert("设置成功！");
                }
            }
        });
    }
</script>

<button onclick="remind({$anchor_id})">开播提醒</button>

2.3 Back-end code

2.3.1 Insert data

<?php
    $user_id = //获取当前用户ID
    $anchor_id = $_POST[&#39;anchor_id&#39;];
    $remind_time = $_POST[&#39;remind_time&#39;];
    $is_reminded = 0;
    //插入数据到数据表
?>

2.3.2 Get the records that need to be reminded

<?php
    $time_now = date("Y-m-d H:i:s");
    $sql = "SELECT * FROM table_name WHERE remind_time <= &#39;{$time_now}&#39; AND is_reminded = 0";
    //执行查询语句，获取需要提醒的记录
?>

2.3.3 Remind users

<?php
    foreach($result as $row){
        $user_id = $row[&#39;user_id&#39;];
        //通过消息推送、邮件等方式提醒用户
        //更新数据表中对应记录的is_reminded字段为1，表示已提醒过
    }
?>

3. Summary

This article briefly introduces how to implement the broadcast reminder function through PHP. Through the cooperation of front-end code and back-end code, users can easily set broadcast start reminders, and at the same time, when the host starts live broadcast, users are automatically reminded to watch the live broadcast. This function can increase the viewing rate of the live broadcast room and is a good choice for live broadcast practitioners.
