Should I use @ in my PHP code?

Question

If I use @ in my code, will it affect performance?

Answer 1

"A foolish consistency is the hobgoblin of little minds." :) To say "never use it" is a bit of an amateurish stance, IMO. I much prefer $var = @$_POST['key'] to $var = isset($_POST['key'])? $_POST['key'] : null;
