<?php
    function base64URLEncode(string $string): string
    {
        // First of all you should encode $data to Base64 string
        $b64 = base64_encode($string);

        // Make sure you get a valid result, otherwise, return FALSE, as the base64_encode() function do
        if ($b64 === false) {
            return false;

The expression return false returns the type false which is incompatible with the type-hinted return string.

        }

        // Convert Base64 to Base64URL by replacing “+” with “-” and “/” with “_”
        $url = strtr($b64, '+/', '-_');

        // Remove padding character from the end of line and return the Base64URL result
        return rtrim($url, '=');
    }
