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

if(isset($_POST['doors'])=== true){
$doors = $_POST['doors'];
}else{$doors = 0;}

if(isset($_POST['windows'])=== true){
$windows = $_POST['windows'];
}else{$windows = 0;}

foreach($doors as $a => $b){

Now you can use $a for each array....

$doors[$a]
$windows[$a]
....
}
