altough this is not a bug, because this is the expected, correct behaviuor, the documentation do not mention this feature, and can be confusing for newbies.

I suggest you reclassify this as a documentation problem.and read this comment http://cl2.php.net/manual/en/control-structures.for.php#42850 to get the result you expect, also make sure to ask in a support forum next time.

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
