What steps can be taken to troubleshoot issues with file downloads not matching the specified file path in PHP scripts?

When file downloads do not match the specified file path in PHP scripts, it could be due to incorrect file paths, permissions issues, or errors in the download code. To troubleshoot this issue, double-check the file path, ensure that the file exists and is accessible, and verify that the download code is correctly implemented. 

// Check if the file exists and is readable
$file_path = '/path/to/file.txt';
if (file_exists($file_path) && is_readable($file_path)) {
    // Set appropriate headers for file download
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="' . basename($file_path) . '"');
    // Output the file for download
    readfile($file_path);
} else {
    echo 'File not found or inaccessible.';
}
