How can debugging tools be utilized to troubleshoot issues with file uploads in PHP scripts?

When troubleshooting file upload issues in PHP scripts, debugging tools like error logs and var_dump can be utilized to identify the root cause of the problem. By checking error logs for any relevant error messages and using var_dump to inspect variables and file upload data, developers can pinpoint where the issue lies and make necessary adjustments to the code. 

<?php
// Check for any file upload errors
if ($_FILES['file']['error'] !== UPLOAD_ERR_OK) {
    error_log('File upload error: ' . $_FILES['file']['error']);
    die('File upload failed. Please try again.');
}

// Debugging file upload data
var_dump($_FILES['file']);

// Process file upload
// Your file upload processing code here

?>
