Bug description: zip_entry_read handling of null byte
Description:
------------
When using zip_entry_read to decompress a zip entry containing a null
byte, the function only returns data up to the first null byte in the
decompressed file. Bug does not occur on PHP 5.1.2 for Windows XP.
Reproduce code:
---------------
<?php
dl("zip.so");
// test.zip contains one file with a null byte in the middle
$zipfile = zip_open("onejpg.zip");
$zipentry = zip_read($zipfile);
zip_entry_open($zipfile, $zipentry);
$content = zip_entry_read($zipentry, zip_entry_filesize($zipentry));
print "filesize: ".filesize("onejpg.jpg")."\n";
print "variable: ";
var_dump($content);
zip_entry_close($zipentry);
zip_close($zipfile);
?>
Expected result:
----------------
var_dump should show a string with the same length as the file size.
To download onejpg.zip and onejpg.jpg, go here:

Actual result:
--------------
var_dump only shows length 4, which is the length up to the null byte.
