Encodes the given data with MIME base64. Base64-encoded data takes about 33% more space than the original data.

<?php 

    function base64url_encode($text){
        $base64 = base64_encode($text);
        $base64url = strtr($base64, '+/=', '-_,');
        return $base64url;
    }
     
    function base64url_decode($text){
        $base64url = strtr($text, '-_,', '+/=');
        $base64 = base64_decode($base64url);
        return $base64;
    }
    ?>
