I use it in front of variables (never tried it on $GLOBALS, etc though)
eg: (using register_globals = on thingo - hey don't blame me, it's the
tech guys who have it on, and there's too much legacy code to turn it off :(
- anyway)
<?
if (@$var) { echo "Yep, var is there"; } else { echo "nope"; }
?>

Subject: [PHP] Re: suppressing errors with "@"
No, it's not a PHP bug. The "@" can not be used before a PHP variables, or
PHP pre-defined variables like $GLOBALS, $_SESSION, $_GET, $HTTP_POST_VARS,
etc. The "@" is used only before the PHP function as far as I know of.
