This is some code from Python:

  hmac_signature = hmac.new(secret_bytes, signed_content.encode(), hashlib.sha256).digest()
  expected_signature = base64.b64encode(hmac_signature).decode()

I need to convert the above exactly into PHP code. I have all the variables (secret_bytes, signed_content)

Then I need to convert the following also into PHP:

if hmac.compare_digest(signature, expected_signature):

I know how a if statement works it’s just the digest command from hmac. I need it all to be in PHP coding.
