How to use PHP to develop video player functions

The video player is one of the commonly used functions in modern websites. It can help the website attract users and provide richer content experience. This article will introduce how to use PHP to develop a simple but practical video player function, with code examples.

1. Design database

First, we need to design a database to store video-related information. Create a database named "videos" that contains a table named "videos". The table should have the following fields:

• id: A unique identifier for the video, using an auto-incrementing primary key.
• title: The title of the video.
• url: The file path of the video.
• thumbnail: The thumbnail path of the video.

After creating the database and tables, we can insert some sample data for demonstration.

2. Create the video player page

Next, we create a file named "video_player.php", which will contain the HTML structure and PHP code of the video player.

First, we need to connect to the database and get video information from the "videos" table. You can use the following code:

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "root", "password", "videos");

// 查询视频信息
$query = "SELECT * FROM videos";
$result = mysqli_query($conn, $query);

// 循环输出视频播放器
while ($row = mysqli_fetch_assoc($result)) {
    $title = $row['title'];
    $url = $row['url'];
    $thumbnail = $row['thumbnail'];

    // 输出视频播放器的HTML结构
    echo '
    <div class="video-container">
        <h2 id="title">'.$title.'</h2>
        <img  src="/static/imghwm/default1.png"  data-src="'.$thumbnail.'"  class="lazy".$thumbnail.'" alt="How to develop video player functionality using PHP" >
        <video src="'.$url.'" controls></video>
    </div>
    ';
}

// 关闭数据库连接
mysqli_close($conn);
?>

The above code loops through the video records in the database and outputs the HTML structure of the video player. Each video contains a title, thumbnail, and video tag, where the video tag contains the path to the video file and has control bars enabled.

3. Beautify the video player

In order to make the video player more attractive and interactive, we can use CSS styles to beautify it. Create a file called "style.css" and add the following code:

.video-container {
    width: 500px;
    margin-bottom: 20px;
}

.video-container h2 {
    margin-top: 0;
}

.video-container img {
    width: 100%;
}

.video-container video {
    width: 100%;
}

The above code sets the width and margins of the video player container, as well as the width of the title, thumbnail, and video.

Finally, introduce the "style.css" file in the "video_player.php" file to apply the style:

<link rel="stylesheet" href="style.css">

4. Test the video player

Now, will Deploy the "video_player.php" file to the server and access the file. You'll see the title, thumbnail, and player for all videos. Click on the player to play the related video.

Through the above steps, we successfully developed a simple but practical video player function using PHP. You can modify and expand it according to actual needs, such as adding user comments, video classification and other functions.
