How to use PHP and CGI to implement the video playback function of the website

In today's multimedia era, video has become an indispensable part of website content. In order to provide a good user experience, the website needs to implement video playback function. This article will introduce how to use PHP and CGI to implement the video playback function of the website, and provide code samples for reference.

1. Preparation
Before starting, you need to ensure that the server has PHP and CGI modules installed. This can be verified by running the phpinfo() function or entering the "php -v" command in the terminal.

2. Create an HTML page
First, you need to create an HTML page as a container for video playback. You can use the following code as a starting point:

<!DOCTYPE html>
<html>
<head>
    <title>视频播放</title>
</head>
<body>
    <video width="640" height="480" controls>
        <source src="video.cgi" type="video/mp4">
    </video>
</body>
</html>

Copy after login

The above code creates a video player with a size of 640x480 and specifies the video source. The path to the video source is "video.cgi", we will create this CGI script in the next steps.

3. Create a CGI script
Next, you need to create a CGI script to handle the request for the video file. CGI scripts can be written using PHP. The following is a simple example:

<?php
$videoPath = "/path/to/video.mp4"; // 设置视频文件的路径

if (file_exists($videoPath)) {
    header("Content-type: video/mp4");
    header("Content-Length: " . filesize($videoPath));

    readfile($videoPath);
} else {
    header("HTTP/1.0 404 Not Found");
    echo "视频文件不存在";
}
?>

Copy after login

The above code first defines the path to the video file and then detects whether the file exists. If present, the correct HTTP headers (Content-type and Content-Length) will be set, and the file content will be read and output to the client. If the file does not exist, a 404 error will be returned.

Make sure to modify the video path to the path of the actual video file so that the code can access and output the video file correctly.

4. Upload video files
Upload the video files that need to be played to the server, and make sure the path of the video files is correct.

5. Test function
Open the HTML page you just created in the browser. You should be able to see a video player and be able to play the uploaded video file normally.

Summary
By using PHP and CGI, we can easily implement the video playback function of the website. Embed the video tag in the HTML page, specify the video source as a CGI script, and then use PHP to write a CGI script to process the request for the video file and output it to the client. I hope this article will help you understand how to implement the video playback function on your website.
