Description:
------------
The following code echoes 3 while it should echo 2.
It should be evaluated as 1 ? 2 : (0 ? 3 : 4). I've no idea how PHP comes up with 3.

Reproduce code:
---------------
echo 1 ? 2 : 0 ? 3 : 4;

Expected result:
----------------
2

Actual result:
--------------
3

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

This is documented.
See the example#3:

Ah, so it's evaluated as (1 ? 2 : 0) ? 3 : 4
Nice, very nice. :(
