Description:
------------
using zip->open(), zip->extractTo on a zip file less than (approx) 250mb works fine. Using it on a file size over 250mb it fails.



Reproduce code:
---------------
$zip = new ZipArchive;
$zip->open("/srv/ftp/bountywin/TEST/IN/Bounty_02695b.zip");
	$zip->extractTo("/srv/ftp/bountywin/TEST/IN/TEMPDATA");
	$zip->close();

Actual result:
--------------
Warning: ZipArchive::extractTo() [function.ZipArchive-extractTo]: Invalid or unitialized Zip object in /srv/www/vhosts/bountywebtest/test/test.php on line 12

Warning: ZipArchive::close() [function.ZipArchive-close]: Invalid or unitialized Zip object in /srv/www/vhosts/bountywebtest/test/test.php on line 13

I finally got the time to sit down and try this bug. I sadly can't reproduce it.

Can you try it again using php 5.2.5?

Please use the following code and paste the result here:

$zip = new ZipArchive;
$r = $zip->open("/srv/ftp/bountywin/TEST/IN/Bounty_02695b.zip");
var_dump($r);

$r = $zip->extractTo("/srv/ftp/bountywin/TEST/IN/TEMPDATA");
var_dump($r);

$r = $zip->close();
var_dump($r);

i have run the revised code, here is the result

int(11)
Warning: ZipArchive::extractTo() [function.ZipArchive-extractTo]: Invalid or unitialized Zip object in /srv/www/vhosts/bountywebtest/test/test.php on line 14
bool(false)
Warning: ZipArchive::close() [function.ZipArchive-close]: Invalid or unitialized Zip object in /srv/www/vhosts/bountywebtest/test/test.php on line 17
bool(false)

We are very pressured, so it may take a while to install an upgrade to php5.2.5. We are running 5.1.6.

The first return value "int(11)" means that the open methods did not find the file or can't open it. Be sure it is in your path. Alternatively you can try using an absolute path.

To test with 5.2.5, you can simply install it locally on your windows and run your script using the command line.

Feel free to come back or ask if you still experience problem to open this archive.

I re-ran after verifying the file name and path:

int(5)
Warning: ZipArchive::extractTo() [function.ZipArchive-extractTo]: Invalid or unitialized Zip object in /srv/www/vhosts/bountywebtest/test/test.php on line 14
bool(false)
Warning: ZipArchive::close() [function.ZipArchive-close]: Invalid or unitialized Zip object in /srv/www/vhosts/bountywebtest/test/test.php on line 17
bool(false)

There is an error while reading.

It is hard to say why, but that's the reason why you get the warnings. The archive was not opened correctly.

Please try using the command line, it will make your tests easier. Maybe it is a permission problem or something else.

I tried this archive locally and it works perfectly. At the very least, I can try to debug on your host directly if you provide me a remote access (don't post it here but per email :).
