The variable is undefined so don't try to use it, period. It's a simple rule that's very easy to follow.

So, the notice shouldn't show up if switch has default action (best implementation). Or not show notices at all (easier). You could say "just turn off notices in production environment". That is not the case. In development environment some scripts can fail because of "Headers already sent". And I don't want to write redundant code such as if(!isset($var))$var=''; Test script: --------------- switch($action){ default: echo 'This shouldn't show a notice!'; break; } Expected result: ---------------- This shouldn't show a notice! Actual result: -------------- Notice: Undefined variable: action in (...) This shouldn't show a notice! ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68105&edit=1
