The assignment to $invoiceID is dead and can be removed.

    echo "Please enter $type ID:";
    $input     = fopen("php://stdin", "r");
    $invoiceID = trim(fgets($input));

It seems like $input can also be of type false; however, parameter $handle of fgets() does only seem to accept resource, maybe add an additional type check?

    fclose($input);

    if (is_numeric($invoiceID)) {
        $invoiceID = intval($invoiceID);
    }
    return $invoiceID;
