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

array_map seems good for this too

$codes = array('tn','us','fr');
$names = array('Tunisia','United States','France');

array_map(function ($code, $name) {
    echo '' . $name . '';
}, $codes, $names);

Other benefits are:

• If one array is shorter than the other, the callback receive null values to fill in the gap.

• You can use more than 2 arrays to iterate through.
