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.

Answer

You can use

hash( 'sha256', $string );
