Toggling in Javascript, PHP and possibly other environments

For a long time if I wanted to change the state of a variable between true and false (toggling). In PHP I would do something like…

$switch = true;
if($switch == true){
    $switch = false;
    $switch = true

That worked fine, then there came Ternary shorthand

$switch = true;
$switch = ($switch == true ? false : true);

Not bad eh? Much easier to read. Then came this

$switch = true;
$switch = !$switch;

If you read it out loud it sounds like, ‘Switch is not true?’ So the answer would be either

True = $switch is false


False = $switch is true
