Key Improvements

Escape Output with htmlspecialchars()

• This ensures any special characters (like &, <, >) in the generated URLs are properly escaped.

Sanitize Input Data

• Check the integrity of $category['slug'] and $d to ensure no unexpected values are used.

Validate the Output

• After running the script, save the output and validate it using an online XML validation tool.
