    $file_handle = fopen($csvFile, 'r');
    while (!feof($file_handle) ) {
        $line_of_text[] = fgetcsv($file_handle, 1024);
    }
    fclose($file_handle);
    return $line_of_text;

You can achieve this using associative arrays.

Replace

$line_of_text[] = fgetcsv($file_handle, 1024);

With

$line = fgetcsv($file_handle, 1024);
$line_of_text[$line[1]] = $line;

This way your function will return something like:

Array
(
    [Andorra] => Array
        (
            [0] => AD
            [1] => Andorra
            [2] => Andorre
        )

    [United Arab Emirates] => Array
        (
            [0] => AE
            [1] => United Arab Emirates
            [2] => Émirats arabes unis
        )

    ....
)

So you will be able to get the row for Anguilla using $line_of_text['Anguilla'].
