Answer 2

The Answer is 17

Answer 3

its 7

Answer 4

It will echo 17
$variable-- is the post decrement operator. First it will give 18 then decrease by one.

If it was like:
$num = 18
echo $num--;

Output would be: 18

Since it is post decrement, directly using it with echo will output original number.
