在PHP中抑制回声通知

Question

I am trying to use echo $var; in my code but sometimes it doesn't exist, so I get a notice from PHP. I don't want to disable all notices from PHP. Is it possible to prevent notice for this statement only?

Note: I tried @echo $var; but it gives me another error. I also found an alternate echo (isset($var) ? $var: ''); but it is quite long and I don't want to type it everytime.

You should be able to use either one of the following

echo @$var;
@print $var;
