Title: Exploring the application of PHP ZipArchive extension in video file compression

Introduction:
In modern society, video files have become one of the important ways for people to communicate and spread information. Faced with the increasing video file size and network transmission bandwidth limitations, it is very necessary to compress videos. This article will introduce the use of PHP ZipArchive extension to realize the compression function of video files in compressed packages, and provide guidance with code examples.

1. Install the PHP ZipArchive extension
Before we begin, we need to install and enable the PHP ZipArchive extension. You can install it through the following command:

sudo apt-get install php-zip

or remove the semicolon in front of extension=zip in the php.ini file and restart the web server.

2. Use PHP ZipArchive extension to implement video compression function

1. Open a compressed package:

   $zip = new ZipArchive();
   if ($zip->open('压缩包路径.zip', ZipArchive::CREATE) === true) {
    echo '成功打开压缩包'. PHP_EOL;
   } else {
    echo '打开压缩包失败'. PHP_EOL;
    return;
   }

2. Traverse the directory and Add video files to the compressed package:

   $dir = '视频目录';
   $files = scandir($dir);
   foreach ($files as $file) {
    if (is_file("$dir/$file")) {
        $ext = pathinfo("$dir/$file", PATHINFO_EXTENSION);
        if (in_array($ext, ['mp4', 'avi', 'mov'])) {  // 视频文件格式可根据需求自行调整
            $zip->addFile("$dir/$file", $file);
            echo "添加文件 $file 到压缩包成功". PHP_EOL;
        }
    }
   }

3. After compressing all video files, close the compressed package:

   $zip->close();
   echo '关闭压缩包'. PHP_EOL;

4. Full code example:

   $zip = new ZipArchive();
   if ($zip->open('压缩包路径.zip', ZipArchive::CREATE) === true) {
    echo '成功打开压缩包'. PHP_EOL;
   } else {
    echo '打开压缩包失败'. PHP_EOL;
    return;
   }
   
   $dir = '视频目录';
   $files = scandir($dir);
   foreach ($files as $file) {
    if (is_file("$dir/$file")) {
        $ext = pathinfo("$dir/$file", PATHINFO_EXTENSION);
        if (in_array($ext, ['mp4', 'avi', 'mov'])) {  // 视频文件格式可根据需求自行调整
            $zip->addFile("$dir/$file", $file);
            echo "添加文件 $file 到压缩包成功". PHP_EOL;
        }
    }
   }
   
   $zip->close();
   echo '关闭压缩包'. PHP_EOL;

   Conclusion:
   This article introduces how to use the PHP ZipArchive extension to implement the compression function of video files in compressed packages. In actual applications, the code can be adjusted and expanded according to needs to meet the implementation of more compression requirements. Of course, we can also combine with other PHP extensions, such as FFmpeg, etc., to achieve richer video processing and compression functions.
