PHP - What's a good way to handle this? - php

Question

OK, let's say when a user selects a country, they are also added with a "federation". These federations are pretty much region-centric.
Let's say I have something like this:
function getFedration($country_iso) {
// 6 federations
// afc = asian nations
// caf = african nations
// cocacaf = north & central america and Caribbean nations
// conmebol = south america
// ofc = Oceanian nations
// uefa = european nations
$afc = array("Japan", "China", "South Korea");
$caf = array("Cameroon", "Chad", "Ivory Coast");
$concacaf = array("United States" , "Canada", "Mexico");
$conmebol = array("Argetina", "Brazil", "Chile");
$ofc = array("Fiji", "New Zealand", "Samoa");
$uefa = array("Spain", "England", "Montenegro");
/*
PSEUDO-code
If $country_iso is in either of six arrays... mark that as the federation...
*/
return $federation;
}
I know, it says a country's name but when it comes down to it, it will be country's iso like JP instead of Japan, CN instead of China, et cetera.
So, I was wondering, is this a feasible thing or is there a better way you'd think?

Answer 1

How about putting all federations into an array, in order to loop through it? Makes things easier, like so:
function countryToFederation($country_iso) {
$federations = array(
"afc" => array("Japan", "China", "South Korea"),
"caf" => array("Cameroon", "Chad", "Ivory Coast"),
"concacaf" => array("United States" , "Canada", "Mexico"),
"conmebol" => array("Argetina", "Brazil", "Chile"),
"ofc" => array("Fiji", "New Zealand", "Samoa"),
"uefa" => array("Spain", "England", "Montenegro"),
);
foreach($federations as $federation) {
if(in_array($country_iso, $federation)) {
return $federation;
}
}
}

Answer 2

If a federation can only belong to one country, I would create one array instead:
$countryToFederationMap = array(
'Japan' => 'AFC',
'China' => 'AFC',
'Cameroon' => 'CAF',
// ...
);
Then the federation is simply:
return $countryToFederationMap[$country];
