dump(true and false) as boolean(true)?

This question already has an answer here:

'AND' vs '&&' as operator 10 answers

and has a lower operator precedence than = so what you are executing is:

($x = true) and false;

So the complete expression - which you don't use the result of - will return false , but $x will be true .

It is because the and operator does not work as you think: 'AND' vs '&&' as operator

Basically, = has higher precedence.

$x = false && true;
var_dump($x);

returns bool(false) .

As does

$x = (false and true);
