Two arrays in foreach loop

Question

I want to generate a selectbox using two arrays, one containing the country codes and another containing the country names.

This is an example:

Answer 1

';

foreach(array_keys($codes) as $i) {

     echo '';
     echo ($i + 1);
     echo '';
     echo $codes[$i];
     echo '';
     echo $names[$i];
     echo '';
}

echo '';

?>
