I would like to know, whether using @ is a good practice. For example, I have an array of unknown length $array.
Is it all right write something like this:
@list($first, $second) = $array;
or is it better to do length check?
Using @ is good practice in any case where you simply *don't care* whether you had an error or not. So if your scripts don't need a value stored in $first or in $second, then you can use the @ operator. But don't use @ in any case where you need to trap for errors (e.g. validating input from $_GET / $_POST).
