This way the archive can be opened for read only access. Regards, Mat ------------------------------------------------------------------------ [2009-07-06 13:21:07] pajoye@php.net It open the files in read/write mode. What do you mean by restricted privileges? Can you describe the exact situation when you get this error (which permissions, context, etc.)? ------------------------------------------------------------------------ [2009-05-10 00:36:24] mb at smartftp dot com Description: ------------ The ZIPArchive->open fails with error 11 when a zip file is opened that has just been created using ZIPArchive. The test code works as expected when running it under administrative privileges. However when running it under restricted access privileges the ZIPArchive->open function is unable to open the file. On the other side readfile() can successfully open the same file. My guess is that the ZipArchive->open functions tries to open the file using a mode other than just read. Reproduce code: --------------- <?php $file = tempnam(sys_get_temp_dir(), 'zip'); print($file . "\n"); $create = new ZipArchive; if($create->open($file, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE )) { for($i=0; $i<10; $i++) { $bogus = "fjewklfj23klfj23lkfj23l"; $create->addFromString($i, $bogus); } if(!$create->close()) { print("close failed"); } } $zip = new ZipArchive(); $open = $zip->open($file); if($open === TRUE) { print("ok\n"); } else { print("error ".$open."\n"); readfile($file); } Expected result: ---------------- ok Actual result: -------------- error 11. content of zip file. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=48218&edit=1
