How can the difference in web server types (Apache/2.0.54 vs. CGI/FastCGI) impact the handling of form data in PHP scripts?

The difference in web server types can impact the handling of form data in PHP scripts due to the way they process and pass the data to the PHP interpreter. When using CGI/FastCGI, the form data is typically passed to PHP as environment variables, while with Apache/2.0.54, the data is passed directly to PHP. To ensure compatibility across different server types, it's recommended to use the `$_REQUEST` superglobal array to access form data, as it combines data from `$_GET`, `$_POST`, and `$_COOKIE`. 

// Access form data using the $_REQUEST superglobal
$username = $_REQUEST['username'];
$email = $_REQUEST['email'];
