Question

I’ve stored countries with their codes in an array like below

$countries = array (
    'AF' => 'Afghanistan',
    'AX' => 'Åland Islands',
    'AL' => 'Albania',
    'DZ' => 'Algeria'
);

Suppose I got the country code ‘AF’ or country name ‘Afghanistan’ from a form, how do I output both the code and name from the array?

The output I’m trying to get is: Afghanistan AF. I’ll later use that in code below.

echo $countries['AF'] gives me the country name, but how do I output both;

Answer 1

If you know the code (‘AF’ in this case

$code = 'AF';
echo 'Country :', $countries[$code], " has code $code\n";

But if you want to got the other way i.e. Afghanistan to get the code AF, you have to iterate throught the list or construct another array.
