I can't reproduce it here (xp sp3 and vista/2k8).

Please provide the file(s) (the minimum required to create a corrupted archive) and the script you are using.

Here is an archive containing both the corrupted file created with the new versions, a good file created with the same script and older version (5.2.6) and the script used - http://rapidshare.com/files/178582253/Error.zip.html

It works just fine here (in apache2 sapi, iis, fcgi and cli).

Can you try the following script please? I suspect some other errors happening and they are not displayed. Be sure to have display_errors activated.

By the way, in the latest releases there are "addFromPattern"/"Glob" functions which let you add recursively something like "*.jpeg" :)

<?php
$path = 'C:\yourpath\\';
$count = 0;


function archive($path, $local)
{
	global $zip, $count;
	if ($handle = opendir($path)) {
		while (($file = readdir($handle)) !== false) {
			if (($file != ".") && ($file != "..")) {
				echo "$file\n";
				var_dump($local, $file, $path);
				if (is_dir($path . $file)) {
					$zip->addEmptyDir($local . $file . "/");
					archive($path . $file . "/", $local . $file . "/");
				} elseif (is_file($path . $file)) {
					if ($count > 128) {
						$zip->close();
						$zip->open($GLOBALS["file"]);
						$count = 0;
					}
					$zip->addFile($path . $file, $local . $file);
					$count++;
				}
			}
		}
		closedir($handle);
	}
	echo "count: $count\n";
}
$file = 't.zip';

$zip = new ZipArchive();

if (($zip->open($file, ZipArchive::CREATE)) === TRUE) {
	archive($path, null);
	$zip->close();

}

echo "done\n";

I have the same issue. It seems that compressing short strings works fine but using huge ones gets them corrupted. Even if the resulting zip might open, using a simple md5 on both files often prove that they differs which is not great...

I downloaded PHP 5.2.6 and replaced the php_zip.dll of 5.2.8 by the 5.2.6 version. It fixed the problem right away. There is really some kind of regression in 5.2.8.

pajoye(at)php(dot)net, here is the output from your script
http://rapidshare.com/files/178740823/ouput.zip.html
(identical with the two versions)
The file working state is the same as with my script
The php(at)undoso(dot)eu's solution is working here too
when combining php5ts.dll version 5.2.9 (CVS)
with php_zip.dll version 5.2.7 (CVS)

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows:

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

Please try a 5.2 snapshot, I committed a fix that should fix this issue.

Now everything is working fine. Thank you very much!

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.

fixed in 5.2, 5.3, head.
