Calling the ``++!++`` or ``++~++`` prefix operator twice does nothing: the second invocation undoes the first. Such mistakes are typically caused by accidentally double-tapping the key in question without noticing. Either this is a bug, if the operator was actually meant to be called once, or misleading if done on purpose.

----

$a = 0;
|
|
$b = false;
|
|
|
|
$c = !!$a; // Noncompliant
|
|
$d = ~~$b; // Noncompliant
