How to Create a Downloadable ZIP Archive of Multiple Files Using PHP?

Creating a ZIP Archive to Download Multiple Files Using PHP

In web development, there are scenarios where you need to provide multiple files for download in a single, compressed package. PHP offers a convenient solution for this task using the ZipArchive class.

Utilizing the ZipArchive Class

To create a ZIP archive, follow these steps:

$zipname = 'file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);

Here, $zip represents the ZIP archive, and $zipname is the desired filename.

Adding Files to the Archive

Once the ZIP archive is created, you can add individual files to it:

foreach ($files as $file) {
  $zip->addFile($file);
}

Replace $files with an array containing the file paths or names.

Closing and Streaming the Archive

After adding all the necessary files, close the archive:

$zip->close();

Now, stream the archive to the client for download:

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);

This code forces the browser to prompt a download box and designates the filename. The file size is specified to resolve compatibility issues in some browsers.

With these steps, you can easily create and download multiple files as a single ZIP archive using PHP.
