I encountered this while using the close/reopen method to avoid using up all available filehandles. On a Windows box the script below runs without errors. Reproduce code: --------------- <?php $za = new ZipArchive; $za->open('./useless.zip', ZipArchive::CREATE); for ($i = 1; $i <= 2000; ++$i) { $file = "$i.txt"; touch($file); if (!$za->addFile("./$file", $file)) { exit("Couldn't add $file"); } echo "Added $file<br />\n"; if ($za->numFiles % 100 == 0) { $za->close(); $res = $za->open('./useless.zip', ZipArchive::CREATE); if ($res !== true) { exit("Close/reopen: Error #$res @ $i"); } echo "Close/reopen @ $i<br />\n"; } } unlink('./useless.zip'); echo 'Done.'; Expected result: ---------------- Added 1.txt Added 2.txt [...] Added 2000.txt Done. Actual result: -------------- Added 1.txt Added 2.txt [...] Added 1299.txt Close/reopen: Error #5 @ 1300 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44974&edit=1
