Description:

originally reported to php-internals here:

pierre has backported a couple functions from 5.3 as a first attempt at patching 5.2.8 here:

http://news.php.net/php.internals/42762

i have not yet tested this patch, but am reporting here first as requested :)

Reproduce code:
---------------

Expected result:
----------------
rangda[/home/sean/ziptest] php ziptest.php                                   :)
opening 'normal' zipfile...ok.
extracted.
opening 'bad' zipfile...ok.
extracted.

(and then two extracted directories should exist)


Actual result:
