Base64_encode for URLS

Question

Is there a base64_encode function that is URL safe in PHP?

It also needs to be decodable obviously.

Thanks for your help!

Answer 1

Try this.

Answer 2

No. There isn't one built-in.

You can simply do this,

$encoded = strtr(base64_encode($data), '+/=', '-_.');
$data = base64_decode(strtr($encoded, '-_.', '+/='));

Answer 3

urlencode(base64_encode($var));
