Description:
------------
PHAR extraction of Zip archives is broken

Reproduce code:
---------------
<?php
// phartest.php
try {
    $phar = new PharData($argv[1]);
    $phar->extractTo('/tmp', null, true); // extract all files, and overwrite
} catch (Exception $e) {
        echo $e;
    // handle errors
}
?>


Expected result:
----------------
When running phartest.php with a zip file, it extracts files with no failure but files contain garbage. File size corresponds but content does not. The script works with TAR or TAR.GZ files seamlessly, so I suspect it's due to some library bug. Files in ZIP archive are compressed with normal Deflate method.

Actual result:
--------------
Hexdump of "phartest.php" extracted from a "phartest.zip" archive containing only the phartest.php script.

My Arch linux system is using zlib 1.2.3.4-3 and no other issues with ZIP files

Seemed to fall over the same issue. However using file_get_contents and manually extract them will return the correct content. But extractTo does not. Using windows 7 and php 5.3.3.

Is this still an issue, if so, do you have a phar zip that I can use to reproduce 
this problem?  Or will any zip do?
