Convert base64URLEncode (in javascript) to php

Question

I have a code in javascript. I want to convert it in php. I don't know how to convert this: str.toString(CryptoJS.enc.Base64)

function base64URLEncode(str) {
  return  str.toString(CryptoJS.enc.Base64).replace(/=/g, '').replace(/\+/g, '-').replace(/\//g, '_');
}

Thank you so much.

Answer 1

So you want to decode base64 in PHP?
