Are there any potential pitfalls in using the "highlight_file" function in PHP for code coloring?

One potential pitfall in using the "highlight_file" function in PHP for code coloring is that it may expose sensitive information, such as database credentials or API keys, if not used carefully. To prevent this, you can sanitize the file path before passing it to the function to ensure only safe files are displayed. 

$filePath = 'path/to/your/file.php';

if (strpos($filePath, 'safe_directory/') === 0) {
    highlight_file($filePath);
} else {
    echo 'Access denied.';
}
