$_SESSION(see PHP: $_SESSION - Manual[^] ) is an associative array containing key value pairs (see PHP: Arrays - Manual[^]). These are not accessed by an index but by their keys which might be integers or strings. Because you have not assigned a value with the key '0' you will get the error. Just use the key instead:echo $_SESSION['username'];
