    text
    copied!<h1>Problem</h1> <p>I am building an online file manager, for downloading a whole directory structure I am generating a zip file of all subdirectories and files (recursively), therefore I use the <code>RecursiveDirectoryIterator</code>. It all works well, but empty directories are not in the generated zip file, although the dir is handled correctly. This is what i am currently using:</p> <pre><code>&lt;?php $dirlist = new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS); $filelist = new RecursiveIteratorIterator($dirlist, RecursiveIteratorIterator::SELF_FIRST); $zip = new ZipArchive(); if ($zip-&gt;open($tmpName, ZipArchive::CREATE) !== TRUE) { die(); } foreach ($filelist as $key=&gt;$value) { $result = false; if (is_dir($key)) { $result = $zip-&gt;addEmptyDir($key); //this message is correctly generated! DeWorx_Logger::debug('added dir '.$key .'('.$this-&gt;clearRelativePath($key).')'); } else { $result = $zip-&gt;addFile($key, $key); } } $zip-&gt;close(); </code></pre> <p>If I ommit the <code>FilesystemIterator::SKIP_DOTS</code> I end up having a <code>.</code> <strong>file</strong> in all directories.</p> <h1>Conclusion</h1> <p>The iterator works, the <code>addEmptyDir</code> call gets executed (the result is checked too!) correctly, creating a zip file with various zip tools works with empty directories as intendet. Is this a bug in phps <code>ZipArchive</code> (<a href="http://www.php.net/manual/en/class.ziparchive.php" rel="nofollow">php.net</a> lib or am I missing something? I don't want to end up creating dummy files just to keep the directory structure intact.</p>
