It seems like some people don't know about '@'. It can be used to ignore the
Undefined variable warning.
'@' is your friend. You can just write:
<?php
@$foo[$bar] += $count;
?>
instead of:
<?php
if (isset($foo[$bar])) $foo[$bar] += $count;
else $foo[$bar] = $count;
?>
But be careful - better only use @ with arrays. Always initialize your scalars.
