How to use PHP ZipArchive to rename and move files in compressed packages?

When developing web applications, we sometimes need to operate the compressed package, such as renaming files in the compressed package or moving files to other directories. In PHP, we can use the ZipArchive library to implement these functions.

ZipArchive is a built-in PHP class used to create, open, read, write and modify ZIP compressed files. It allows us to perform various operations on compressed files, including file renaming and moving.

The following is a sample code that uses the PHP ZipArchive class to rename and move files in a compressed package:

<?php
// 压缩包路径
$zipPath = 'path/to/archive.zip';

// 新文件名和路径
$newFileName = 'new-file.txt';
$newFilePath = 'path/to/new/location/' . $newFileName;

// 创建ZipArchive对象
$zip = new ZipArchive;

// 打开压缩包
if ($zip->open($zipPath) === true) {

    // 获取原文件名和路径
    $originalFileName = 'old-file.txt';
    $originalFilePath = 'path/to/original/location/' . $originalFileName;

    // 获取文件在压缩包中的索引
    $fileIndex = $zip->locateName($originalFilePath);

    // 如果文件存在于压缩包中
    if ($fileIndex !== false) {

        // 重命名文件
        $zip->renameName($originalFilePath, $newFilePath);

        // 移动文件
        $zip->extractTo('path/to/extract/to/');

        echo '文件重命名和移动成功！';
    } else {
        echo '文件不存在于压缩包中！';
    }

    // 关闭压缩包
    $zip->close();

} else {
    echo '无法打开压缩包！';
}
?>

In the above example, we first specify the path of the compressed package $zipPath , and defines the file names and paths of the original files and new files to be renamed.

Then, we create a ZipArchive object and use the open() method to open the compressed package. If the compressed package is successfully opened, we use the locateName() method to obtain the index of the file in the compressed package based on the original file path.

If the file exists in the compressed package, we use the renameName() method to rename the file to a new file name and path. Then, we use the extractTo() method to extract the files from the compressed package to the specified target path.

Finally, we use the close() method to close the compressed package and display the corresponding message based on the operation results.

The above is the sample code for using the PHP ZipArchive class to rename and move the files in the compressed package. You can modify and extend it according to your needs. Hope this article is helpful to you!
