What is the main issue the user is facing when trying to pack a ZIP file in PHP?

The main issue the user is facing when trying to pack a ZIP file in PHP is that they may not have the ZipArchive extension enabled in their PHP installation. To solve this issue, they need to make sure that the ZipArchive extension is installed and enabled in their PHP configuration. 

// Check if ZipArchive extension is enabled
if (!extension_loaded('zip')) {
    echo 'ZipArchive extension is not enabled. Please enable it in your PHP configuration.';
    exit;
}

// Code to pack files into a ZIP archive
$zip = new ZipArchive();
$zipFileName = 'archive.zip';

if ($zip->open($zipFileName, ZipArchive::CREATE) === TRUE) {
    $fileToZip = 'file.txt';
    $zip->addFile($fileToZip);
    $zip->close();
    echo 'Files packed into ZIP archive successfully.';
} else {
    echo 'Failed to create ZIP archive.';
}
