[RESOLVED] variable equals to true and false

Hello fellow programmers.

I was in this job interview and got a test with different tasks. One of them was the following:

What's the output of

<?php
$x = ($y = true and false);
var_dump($x);
var_dump($y);
?>

the output is the following:
bool(false) bool(true)

could anyone explain me why $x becomes false and $y becomes true?

Thanks in advance,
Faifas

Operator precedence. The code is exactly the same as

$x = (($y = true) and false);

Which you could write like

$y = true;
$x = ($y and false);

aha, I see, but what exactly does the part

($y and false);

do?

It's a logical and, meaning it does the same thing as &&.

Just remember that && has higher precedence than = which has higher than and.
So $x = ($y = true && false) is the same as $x = ($y = (true && false))

I get your point, thanks for information!
