How to create a video playlist using PHP?

With the improvement of network speed and the development of video technology, video is used more and more widely on the Internet. In order to better organize and manage a large number of video resources, we can use PHP to create a video playlist. This article will introduce in detail how to use PHP to implement this function, with corresponding code examples.

First, we need to create a database table containing video resource information. We can use the MySQL database to create a table named videos, containing the following fields: id (video ID), title (video title), url (video address) and thumbnail (thumbnail address). The table can be created using the following SQL statement:

CREATE TABLE `videos` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  `url` varchar(255) NOT NULL,
  `thumbnail` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Next, we can use PHP to connect to the database and query the data of the video list. In the page, we can use the HTML5 <video> tag to display the video, and use the <img src="/static/imghw/default1.png" data-src="'.$row[" class="lazy" alt="How to create a video playlist using PHP?" > tag to display the video thumbnail. The following is a simple sample code:

<?php
// 连接数据库
$conn = new mysqli("localhost", "username", "password", "database");

// 检查连接是否成功
if($conn->connect_error) {
    die("数据库连接失败: " . $conn->connect_error);
}

// 查询视频列表数据
$sql = "SELECT id, title, url, thumbnail FROM videos";
$result = $conn->query($sql);

// 输出视频列表
if($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo '<div class="video-item">';
        echo '<h3 id="row-title">'.$row["title"].'</h3>';
        echo '<a href="'.$row["url"].'"><img src="/static/imghw/default1.png"  data-src="'.$row["  class="lazy".$row["thumbnail"].'" alt="'.$row["title"].'"></a>';
        echo '</div>';
    }
} else {
    echo "暂无视频";
}

// 关闭数据库连接
$conn->close();
?>

In the above code, we first establish a database connection, and then execute the query statement to obtain the data of the video list. Next, the title, video address, and thumbnail address of each video are output through a loop. Finally, close the database connection.

This is just a simple example and can be expanded according to actual needs. For example, you can add paging function to display more videos; you can use AJAX to load the video list asynchronously, and so on.

Of course, creating a video playlist is not just about displaying video information, but also considering other functions, such as video classification, tags, sorting, etc. These can be expanded and optimized based on actual needs.

To sum up, using PHP to create video playlists can help us better manage and display a large number of video resources. With database support, we can easily add, delete and modify video information. Of course, in addition to code implementation, a good user interface and user experience are also very important. I hope the introduction in this article can help you.
