World nations on one php array, better if static?

I'm working on a site where the user can select his country, for now I've created an array which contains alla nation names and relative codes like it code for Italy:

<?php
$nations[] = array ("code" => "af", "name" => "Afghanistan");
$nations[] = array ("code" => "ax", "name" => "Aland Islands");
$nations[] = array ("code" => "al", "name" => "Albania");
$nations[] = array ("code" => "dz", "name" => "Algeria");
$nations[] = array ("code" => "as", "name" => "American Samoa");
$nations[] = array ("code" => "ad", "name" => "Andorra");
$nations[] = array ("code" => "ao", "name" => "Angola");
$nations[] = array ("code" => "ai", "name" => "Anguilla");
$nations[] = array ("code" => "aq", "name" => "Antartica");
$nations[] = array ("code" => "ag", "name" => "Antigua and Barbuda");
$nations[] = array ("code" => "ar", "name" => "Argentina");
$nations[] = array ("code" => "am", "name" => "Armenia");
$nations[] = array ("code" => "aw", "name" => "Aruba");
$nations[] = array ("code" => "au", "name" => "Australia");
$nations[] = array ("code" => "at", "name" => "Austria");
$nations[] = array ("code" => "az", "name" => "Azerbaijan");
$nations[] = array ("code" => "bs", "name" => "Bahamas");
$nations[] = array ("code" => "bh", "name" => "Bahrain");
$nations[] = array ("code" => "bd", "name" => "Bangladesh");
// etc... for 245 array elements
?>

when I load the page where user can select his country I use a function to print all the data:

<?php

function get_nation_name ($code = "") {
    global $nations;
    for ($n = 0; $n < count ($nations); $n ++) {
        if ($code == $nations[$n]["code"]) return $nations[$n]["name"];
    }
}

function nation_select_option ($attributes, $code = "") {
    global $nations;
    $nation_name = get_nation_name ($code);

    $html = "   <select $attributes>\r";
    for ($n = 0; $n < count ($nations); $n ++) {
        if ($nation == $nations[$n]["code"]) $html .= "     <option selected=\"selected\" value='".$nations[$n]["code"]."'>".$nations[$n]["name"]."</option>\r";
        else $html .= "     <option value='".$nations[$n]["code"]."'>".$nations[$n]["name"]."</option>\r";
    }
    $html.= "   </select>\r";

    return $html;
}

?>

this is useful, because if the user has already chosen a nation, he can load the entire list with the previous one selected, but it's not properly light!

should I use another way to do that or could it be enough optimized?

<?php

print nation_select_option ('id="my_css_id"', "ar"); // ar => Argentina code
?>

I'd do it like this:

It's always better to use keys that make sense in an array so you don't have to iterate through it to retrieve the value you need.


Unelss it's necessary to show all 200+ countries, I'd suggest doing this perhaps in the form of a suggestion/searchbox. The user types in 'afg' and you asynchrounously return:

'Afghanistan'

There's no sense in displaying what the user doesn't need :)
