Translate a piece of code from python to php?

Question

PHP

Good evening. I am not familiar with python at all, you need to translate this piece of code into php.
There is this piece of code

import hashlib 
def _get_sign(request, keys_required, secret): 
keys_sorted = sorted(keys_required)
string_to_sign = ":".join(request[k].encode("utf8") for k in keys_sorted]) + secret 
sign = hashlib.md5(string_to_sign).hexdigest() 
return sign

Thanks in advance
