in reply to Auto-increment frenzy

Interesting, although it might have been more interesting had you given the expect results. I would expect
  1. 3
  2. 3
  3. 2

    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.
