How Can I Efficiently Generate a Selectbox from Two Parallel Arrays of Country Codes and Names?

Iterating and Printing Values Concurrently from Arrays of Matching Length

This question addresses the task of generating a selectbox from two arrays of equivalent sizes, with one array holding country codes and the other holding corresponding country names. An initial attempt utilizing a "foreach" loop with the keyword "and" failed to achieve the desired result. The solution provided suggests alternative approaches:

1. Using Loop Indices:

   A "foreach" loop with an index can establish a connection between corresponding values in the arrays. For instance:

   foreach( $codes as $index => $code ) {
      echo '<option value="' . $code . '">' . $names[$index] . '</option>';
   }

2. Associative Array:

   Restructuring the country code array as an associative array, with codes as keys and names as values, provides a more concise solution. This method allows values to be accessed directly using the corresponding code keys:

   $names = array(
      'tn' => 'Tunisia',
      'us' => 'United States',
      ...
   );

   Copy after login
