Comment puis-je télécharger un dossier en tant que fichier Zip?

Question

J'ai un dossier avec des images sur mon site Web. Quand je charge ma page, un téléchargement automatique du dossier comme Zip-File devrait commencer.

$dir = 'gallery/1/'; 
$zip_file = 'file.zip'; 

// Get real path for our folder 
$rootPath = realpath($dir); 

// Initialize archive object 
$zip = new ZipArchive(); 
$zip->open($zip_file, ZipArchive::CREATE | ZipArchive::OVERWRITE); 

// Create recursive directory iterator 
/** @var SplFileInfo[] $files */ 
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($rootPath), 
    RecursiveIteratorIterator::LEAVES_ONLY 
); 

foreach ($files as $name => $file) 
{ 
    // Skip directories (they would be added automatically) 
    if (!$file->isDir()) 
    { 
     // Get real and relative path for current file 
     $filePath = $file->getRealPath(); 
     $relativePath = substr($filePath, strlen($rootPath) + 1); 

     // Add current file to archive 
     $zip->addFile($filePath, $relativePath); 
    } 
} 

// Zip archive will be created only after closing object 
$zip->close(); 


header('Content-Description: File Transfer'); 
header('Content-Type: application/octet-stream'); 
header('Content-Disposition: attachment; filename='.basename($zip_file)); 
header('Content-Transfer-Encoding: binary'); 
header('Expires: 0'); 
header('Cache-Control: must-revalidate'); 
header('Pragma: public'); 
header('Content-Length: ' . filesize($zip_file)); 
readfile($zip_file); 

Mais lorsque je charge ma page, rien ne se passe.

Le code PHP doit figurer en haut de la page. Il ne devrait pas y avoir d'autre code html avant cela
