 New Comment:

I can provide additional example zip files that fail. 
This problem causes my website performance to plummet 
occaisionally, requiring a restart of Apache.  
I'd be happy to help evaluate fixes, or to know of 
any possible work-arounds.

Your file is corrupted. It contains invalid crc, compressed and uncompressed data lenghts of
archived file.
It is libzip related bug. More details here http://nih.at/listarchive/libzip-discuss/msg00074.html.

Description:
------------
The files joined contained: the script example.php and the archive example.zip.

I can unzip the example.zip with the following commandlines:
unzip example.php
iconv -f UTF16 -t UTF8 data
( show the data xml values ).

But the test script failed to unzip the compressed file.

Test script:
---------------
$zip = new ZipArchive ();
$zip->open( 'example.zip' );
$f = $zip->getStream ('data');
 while (!feof($f)) {
  echo fgets($f);
} 
fclose($f);
$zip->close();

Expected result:
----------------
not to go in infinite loop.

Actual result:
--------------
don't work. Please send me an email to have the example.zip
