Question

I am using a php script to unzip ZIP file. but this script unzip only one level of directories without extracting the sub directories of that file
the script:

$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
    $zip->extractTo('/my/destination/dir/');
    $zip->close();
    echo 'ok';
} else {
    echo 'failed';
}

for example: if the test.zip contains 2 folders: folder1\file.png, folder2\folder3\file3.png

after extracting this ZIP file, i only see the folder1*.* and folder2*.* but without the sub directory folder3.

How can i improve it?
