How can one effectively troubleshoot and debug issues related to ZIP file creation in PHP, especially when the desired output is not achieved?

To effectively troubleshoot and debug issues related to ZIP file creation in PHP, one can start by checking for any errors or warnings generated during the creation process. Additionally, verifying that the correct file paths and permissions are set for the files being added to the ZIP archive can help resolve issues. Using PHP's built-in functions like `zip_open`, `zip_add`, and `zip_close` can also aid in debugging problems with ZIP file creation. 

<?php
$zip = new ZipArchive();
$zipFileName = 'example.zip';

if ($zip->open($zipFileName, ZipArchive::CREATE) === TRUE) {
    // Add files to the ZIP archive
    $zip->addFile('file1.txt');
    $zip->addFile('file2.txt');
    
    // Close the ZIP archive
    $zip->close();
    
    echo 'ZIP file created successfully';
} else {
    echo 'Failed to create ZIP file';
}
?>
