Edit report at https://bugs.php.net/bug.php?id=59118&edit=1 ID: 59118 Comment by: marco dot clemencic at gmail dot com Reported by: niculaantoniu at yahoo dot com Summary: Can not open more than 65535 entries Status: No Feedback Type: Bug Package: Zip Related Operating System: windows XP PHP Version: 5.2.0 Assigned To: cmb Block user comment: N Private report: N New Comment: For reference, I stumbled on this bug using PHP 5.3.3 (on a system equivalent to RedHat 6). I found out that the problem was solved by the upgrade of libzip to 0.10, see https://libzip.org/news/release-0.10.html Cheers Marco Previous Comments: ------------------------------------------------------------------------ [2015-05-17 04:22:20] php-bugs at lists dot php dot net No feedback was provided.

" "; print_r($zip->statIndex($i)); } $zip->close(); ?> Do you still experience this issue with current PHP versions? If so, we'd need further details, ideally a copy of an archive that shows the behavior. ------------------------------------------------------------------------ [2010-03-19 15:04:12] niculaantoniu at yahoo dot com "The original ZIP format had a 4GB limit on various things (uncompressed size of a file, compressed size of a file and total size of the archive), as well as a limit of 65535 entries in a zip archive. In version 4.5 of the specification (which is not the same as v4.5 of any particular tool), PKWARE introduced the "ZIP64" format extensions to get around these limitations. Zip64 support is emerging. For example, the File Explorer in Windows XP does not support ZIP64, but the Explorer in Windows Vista does. Likewise—some libraries, such as DotNetZip and IO::Compress::Zip in Perl, support ZIP64, while others, such as Java's built-in java.util.zip, still lack it." http://en.wikipedia.org/wiki/ZIP_file_format#ZIP64 ------------------------------------------------------------------------ [2010-03-15 14:09:11] niculaantoniu at yahoo dot com Description: ------------ I have an archive with more than 65535 entries. The ZipArchive and the zip functions can process only 65535 entries Reproduce code: --------------- $zip = new ZipArchive(); $zip->open($cwd."/thezip.zip", ZIPARCHIVE::CHECKCONS); for ($idx = 0 ; $idx<70000; $idx++){ echo "<br>".$idx." "; print_r($zip->statIndex($idx)); //echo $zip->getFromIndex($idx); } Expected result: ---------------- 70000 entries statistics Actual result: -------------- i will show echo 70000 lines but the last with stat info is the 65534 line ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=59118&edit=1
