Symfony2 create and download zip file

Question

I have one application that upload some files and then I can compress as zip file and download.

The export action:

public function exportAction() {

ZipArchive creates the zip file into the root directory of your website if only a name is indicated into open function like $zip->open("document.zip", ZipArchive::CREATE). Specify the path into this function like $zip->open("my/path/document.zip", ZipArchive::CREATE). Do not forget delete this file with unlink() (see doc).

Here you have an example in Symfony 4 (may work on earlier version):

use Symfony\Component\HttpFoundation\Response;
use \ZipArchive;

public function exportAction()
{
    // Do your stuff with $files
    
    $zip = new ZipArchive();
    $zip_name = "../web/zipFileName.zip"; // Users should not have access to the web folder (it is for temporary files)
    // Create a zip file in tmp/zipFileName.zip (overwrite if exists)
    if ($zip->open($zip_name, ZipArchive::CREATE | ZipArchive::OVERWRITE) === TRUE) {
           
         // Add your files into zip
         foreach ($files as $f) {
            $zip->addFromString(basename($f),  file_get_contents($f)); 
         }          
         $zip->close();
    
         $response = new Response(
            file_get_contents($zip_name),
            Response::HTTP_OK,
            ['Content-Type' => 'application/zip', 
             'Content-Disposition' => 'attachment; filename="' . basename($zip_name) . '"',
             'Content-Length' => filesize($zip_name)]);

         unlink($zip_name); // Delete file

         return $response;
     } else {
            // Throw an exception or manage the error
     }
}

You may need to add "ext-zip": "*" into your Composer file to use ZipArchive and extension=zip.so in your php.ini.
