What are the potential differences in folder structure when creating and extracting Zip files using different Zip programs in PHP?

When creating and extracting Zip files using different Zip programs in PHP, there may be potential differences in the folder structure due to variations in how each program handles paths and directories. To ensure consistency, it is recommended to use a standardized approach for creating and extracting Zip files. 

// Create a Zip file with a consistent folder structure
$zip = new ZipArchive();
$zipFileName = 'example.zip';

if ($zip->open($zipFileName, ZipArchive::CREATE) === TRUE) {
    $files = glob('path/to/files/*');
    
    foreach ($files as $file) {
        $localName = basename($file);
        $zip->addFile($file, $localName);
    }
    
    $zip->close();
} else {
    echo 'Failed to create Zip file';
}

// Extract a Zip file with a consistent folder structure
$zip = new ZipArchive();
$zipFileName = 'example.zip';
$extractPath = 'path/to/extract';

if ($zip->open($zipFileName) === TRUE) {
    $zip->extractTo($extractPath);
    $zip->close();
    echo 'Zip file extracted successfully';
} else {
    echo 'Failed to extract Zip file';
}
