Complete implementation tutorial of PHP broadcast reminder function
In the current Internet era, live broadcast has become a popular way of social entertainment, attracting A large number of viewers and anchors. In order to improve user experience, many live broadcast platforms provide a broadcast start reminder function, so that users can receive timely notifications when their favorite anchors start broadcasting. This article will introduce in detail how to use PHP to implement a simple broadcast reminder function, and attach specific code examples.
1. Create a database table
First we need to create a database table to store the user's broadcast reminder information. The following is a simple example table structure:
CREATE TABLE `reminders` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` int(11) NOT NULL, `streamer_id` int(11) NOT NULL, PRIMARY KEY (`id`) );
2. Write PHP code
a. Connect to the database
First, we need to write PHP code to connect to the database. The following is a sample code:
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
?>b. Add a reminder
Next, we need to write PHP code to add a reminder. After the user clicks the reminder button, the user ID and anchor ID are inserted into the database table. The following is a sample code:
<?php
if(isset($_POST['user_id']) && isset($_POST['streamer_id'])){
$user_id = $_POST['user_id'];
$streamer_id = $_POST['streamer_id'];
$sql = "INSERT INTO reminders (user_id, streamer_id) VALUES ('$user_id', '$streamer_id')";
if ($conn->query($sql) === TRUE) {
echo "Reminder added successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
}
?>c. Get reminder
Finally, we need to write PHP code to obtain the user's reminder information. The following is a sample code:
<?php
$user_id = 1; // 假设用户ID为1
$sql = "SELECT streamer_id FROM reminders WHERE user_id='$user_id'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
echo "Streamer ID: " . $row["streamer_id"];
}
} else {
echo "No reminders found for user ID: '$user_id'";
}
?>3. Front-end page
Finally, we can set a reminder button on the front-end page and use Ajax requests to trigger the action of adding a reminder. The following is a simple sample code:
<!DOCTYPE html>
<html>
<head>
<title>Live Streaming Reminder</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
<body>
<button id="remind" data-user="1" data-streamer="123">Set Reminder</button>
</body>
<script>
$("#remind").click(function(){
var user_id = $(this).data("user");
var streamer_id = $(this).data("streamer");
$.post("add_reminder.php", { user_id: user_id, streamer_id: streamer_id }, function(data){
alert(data);
});
});
</script>
</html>Through the above steps, we can implement a simple PHP broadcast reminder function. When the user clicks the reminder button, the system will store the user ID and anchor ID in the database. The user can also obtain the reminder information through the front-end page. Of course, this is just a simple example, and more functions can be expanded and optimized according to needs in actual applications. I hope this tutorial can help developers in need.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
