You need at least version PHP 5.6.0 to use that function. — Thank you for your time, Mark “Dygear” Tomlin.

Wait. We have this code there for old PHP versions:

// for php < 5.6.0
if(!function_exists('hash_equals'))
{
	function hash_equals($str1, $str2)
	{
		if(strlen($str1) != strlen($str2))
			return false;
		else {
			$res = $str1 ^ $str2;
			$ret = 0;
			for($i = strlen($res) - 1; $i >= 0; $i--)
				$ret |= ord($res[$i]);
			return !$ret;
		}
	}
}

Normally, this should ensure compatibility with older PHP versions. Either we should make that code work or drop it and raise the required PHP version.
I will first check why it does not work.

The reason is, as I guessed, the order:
The workaround function is placed in lines 4194-4208.
It is used in lines 4243, 4245, 4251 and 4350.
These calls are in the Authorization constructor, which is called in line 760.
Therefore, at this point in time, the workaround code has not been called and the function is still undefined.

We would need to move the workaround code above line 760...

It seems PHP 5.3 is still used quite a lot: https://w3techs.com/technologies/details/pl-php/5/all
So I guess I will fix this and release an 1.9.8.1 ;-)

Should be fixed with version 1.9.8.1 released just now.
