I have this php code:
$password = sha256($_POST['password']);
but when I run this code it says:
Fatal error: Call to undefined function sha256() in .... on line ...ix it as
What is wrong with this code and what must I do to fix this as I know that sha256 exists.
I have also tried:
$password = sha256(trim($_POST['password']));
But that doesn't work either.
