the '@' is most valuable when you're requesting variables that have been
POSTed or REQUESTed:
@$Name = $_POST['Name'];
So, in case someone DIDN'T fill out the field 'Name', the script won't go
all ugly. It lets you handle errors gracefully. Without the @ in the
above line, the output would be "Notice: Undefined Variable 'Name'" or
something. Instead I can just add:
if ($vName=="") {
echo "Sorry, please fill out your name.";
exit;
}
.... to handle the error gracefully...
