When using libxml functions in PHP, you can handle errors by checking the return values of the functions. Many libxml functions return false or other specific values to indicate an error. By checking these return values, you can detect errors and take appropriate actions, such as displaying an error message, logging the error, or executing alternative code paths. Additionally, you can use conditional statements and error handling techniques like try-catch blocks to handle exceptions that may occur during function execution. It's important to handle errors effectively to ensure proper XML processing and manipulation in PHP.
