Using (@) error suppression on Undefined Variables

[eluser]bigtony[/eluser]
It's VERY bad practice to use undefined variables, and therefore the use of @ should only be needed on rare occassions.

If you are using CI sessions then the variable won't be undefined in any case:

Code:

$logged_in = $this->session->userdata('logged_in');

The above will set $logged_in to FALSE if the actual logged_in value (in the session) is undefined. So you then won't need to use @.
