What are the potential pitfalls of using both GET and POST methods in PHP forms?

Using both GET and POST methods in PHP forms can lead to confusion and potential security vulnerabilities. It is recommended to choose one method (usually POST) for submitting form data to ensure consistency and security. If you need to access URL parameters, you can do so separately from the form submission. 

// Example of accessing URL parameters separately from form submission
if(isset($_GET['param'])){
    $param = $_GET['param'];
    // Use the parameter as needed
}

if($_SERVER['REQUEST_METHOD'] == 'POST'){
    // Process form submission using POST method
}
