Strtolower when passing a session to a variable, is it legal?

Can this be done?

$author = strtolower($_SESSION['valid_username']);

      

I want to enter all authors in the table as lower case.

Yes, this option is as long as it is $_SESSION['valid_username']

set, otherwise you will receive a notification (if your error reporting is set so low).



You can check if it exists with if (isset($_SESSION['valid_username']))

Yes.

$_SESSION['valid_username']

      



is a session variable that evaluates a string, so passing it as a parameter to the strtolower function is not a problem.
