Use of @ with Variables

[Anon]

I've seen the @ symbol used to hide error messages resulting from function calls, but what does it do when applied to a variable? As shown in http://www.phpbuilder.com/columns/mattias20000312.php3?page=2

Thanks,

I think it stops PHP's 'undeclared variable' warnings.

Most people don't have error reporting set that high so don't get these messages anyway.
