Submitted: 2009-07-03 17:51 UTC Modified: 2009-08-02 22:20 UTC

Description:
------------
If I try to read content.xml of an odt file (just a few lines, tried several files, created with different odt version on different plattforms), it always fails with error message the zip file is corrupted. Open Office itself, unzip or kde's ark can read it without problem. So I think the problem is related the zip implementation in phar.
I get the same result with php5.2.9 under openSUSE11.0.
Reading the directory with:
   php -r "print_r(scandir('phar://test.odt/'));" 
shows the files and gives no error or warning.

Reproduce code:
---------------
php -r "echo file_get_contents('phar://test.odt/content.xml');"

Expected result:
----------------
xml of odt content

Actual result:
--------------
PHP Warning:  file_get_contents(phar://test.odt/content.xml): failed to open stream: phar error: internal corruption of zip-based phar "/root/test.odt" (local header of file "content.xml" does not match central directory) in Command line code on line 1

please provide a link to an actual odt file that fails which I can use in a test case to reproduce the problem (no GPL things in it please)

Here's my test file: https://pole.outdoor-training.de/test.odt
Thought so far I was not able to produce an oo3 file, which can be read with phar.
Thanks for looking into it :-)

Please try using this snapshot:

  http://snaps.php.net/php5.3-latest.tar.gz
 
For Windows:

  http://windows.php.net/snapshots/

this is a fascinating issue - the fix was implementing the data descriptor part of the zip standard.  I didn't think anyone actually used that in modern ZIP implementations, since it is designed for creating streamed zip files, but I guess I was wrong.

:)
