What are some alternative methods or best practices for creating empty directories in zip files using PHP?

When creating zip files using PHP, empty directories are not included by default. To include empty directories in zip files, you can create placeholder files within the empty directories before adding them to the zip archive. This ensures that the empty directories are preserved when the zip file is extracted. 

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

// Add empty directory with placeholder file
$emptyDirName = 'empty_directory/';
$zip->addEmptyDir($emptyDirName);
$zip->addFromString($emptyDirName . '/placeholder.txt', '');

$zip->close();
