How can PHP be used to handle links with GET variables for include() functionality?

When using include() to include files with GET variables in PHP, the variables need to be properly encoded to prevent errors and security vulnerabilities. This can be done using the http_build_query() function to encode the variables into a query string. By passing the encoded query string as a parameter to the included file, you can ensure that the GET variables are handled correctly. 

$variables = array(
    'id' => 123,
    'name' => 'John Doe'
);

$queryString = http_build_query($variables);
include('example.php?' . $queryString);
