How does PHP ZipArchive rename the compressed package file?

During the PHP development process, we often need to process compressed files, such as decompression, compressed files, etc. For already created compressed files, sometimes it is necessary to rename the internal files. PHP provides the ZipArchive class to process compressed files. We can use the methods in this class to rename compressed files.

First, we need to create a ZipArchive object and open the existing compressed package file. The code is as follows:

$zip = new ZipArchive();
if ($zip->open('example.zip') === TRUE) {
    // 压缩包打开成功
} else {
    // 压缩包打开失败
}

Next, we need to get the list of all files in the compressed package. You can use the getFromName method to obtain the data of the specified file, and then use the renameName method to rename the file. The code is as follows:

$fileName = 'oldName.txt';
$newFileName = 'newName.txt';

$fileIndex = $zip->locateName($fileName); // 获取文件在压缩包中的索引
if ($fileIndex !== false) {
    $zip->renameName($fileName, $newFileName); // 对文件进行重命名
    $zip->close(); // 关闭压缩包
    echo "文件重命名成功！";
} else {
    echo "未找到指定文件！";
}

In the above code, we pass in the file name to be renamed and the new file name, and then obtain the index of the file in the compressed package through the locateName method. If the file exists, call the renameName method to rename the file and close the compressed package file. If the file does not exist, a prompt message indicating that the specified file is not found is output.

Finally, remember to close the compressed package file after the operation is completed. This can be achieved by calling the close method. The code is as follows:

$zip->close();

Overall, through the locateName and renameName methods provided by the ZipArchive class, we can easily rename the compressed package file. The above is a simple example that can be modified and expanded according to actual needs.
