PHP equivalent of hmac.new(secret, message, hashlib.sha256).hexdigest()

hmac-sign.php

<?php

$message = 'Message';
$secret = 'secret';

print "php\n";
print hash_hmac('SHA256', $message, $secret) . "\n";

hmac-sign.py

import hmac
import hashlib

message = 'Message'
secret = 'secret'

print 'python'
print hmac.new(secret, message, hashlib.sha256).hexdigest()

output.log

$ python bin/hmac-sign.py && php bin/hmac-sign.php

I have a python3 script that works to call an API, but I need to reproduce in PHP as it will be used in a wordpress site and calling out to run a python script is proving difficult on my client's (godaddy) server.

`unixtime = time.time()
body = '{"timestamp":' + str(unixtime) + '}'
 
secretBytes = bytearray.fromhex(secret)

bodyBytes = bytearray(body, "utf8")

signature = hmac.new(secretBytes, bodyBytes, digestmod=hashlib.sha256).hexdigest()`

the php equivalent hash_hmac() isn't working. Thoughts?

@knoxtechnology I know it's been a while but did you ever find a solution for this?
