just to expand on @B.Mossavari answer, you should check the key is there before extracting the value or PHP will return a undefined index Notice

if (array_key_exists($country_code, $countries)) {
    $value = $countries[$country_code];
} else {
    $value = ''; // set value to something so your code doesn't fail later 
}

this is my preferred way, but you could also check using isset($countries[$country_code]) or !empty($countries[$country_code])

According to php documentation:

Array elements can be accessed using the array[key] syntax.

In your code it will looks like: $value = $countries[$country_code];

Also I recommend you to read about arrays in PHP here: http://php.net/manual/en/language.types.array.php your case is explained in 6th example.

You may get it this way

$value = $countries[$country_code];
