Are there any alternative methods or libraries that can be used for zipping and downloading files in PHP to avoid potential pitfalls?

When zipping and downloading files in PHP, it is important to be cautious of potential pitfalls such as memory exhaustion or file corruption. One alternative method to avoid these issues is to use the ZipArchive class in PHP, which provides a more reliable and efficient way to create zip files. By using ZipArchive, you can add files to the zip archive one by one without loading them all into memory at once, reducing the risk of memory exhaustion. 

// Create a zip file and add files to it using ZipArchive
$zip = new ZipArchive();
$zipFileName = 'example.zip';

if ($zip->open($zipFileName, ZipArchive::CREATE) === TRUE) {
    $files = ['file1.txt', 'file2.txt', 'file3.txt'];

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

    $zip->close();

    // Download the zip file
    header('Content-Type: application/zip');
    header('Content-Disposition: attachment; filename="'.basename($zipFileName).'"');
    header('Content-Length: ' . filesize($zipFileName));
    readfile($zipFileName);
} else {
    echo 'Failed to create zip file';
}
