in thread Auto-increment frenzy

As long as we are on the subject of expectations, I was expecting:
  1. 5 (the first $a++ assigns 2 to $a, the second $a++ assigns 3, and then $a = 3 + 2). Or the flying pigs out of my nose.
  2. 3
  3. 3

    the first $a++ assigns 2 to $a, the second $a++ assigns 3, and then $a = 3 + 2
    well, I would expect that the post increment actually postincrements:
    $a++ returns $a and increments after that; so the first $a++ returns 1 and now $a is 2, the second increment returns 2 and makes $a = 3
    so the addition returns 1 + 2 = 3.
    He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.
