Question

My file structure in zip is

lib
css
js
app1
app2
index.php

All the above files and folders are in test.zip

i want to extract this test.zip using php

$zip = new ZipArchive;
    $res = $zip->open("test.zip");
    if ($res === TRUE)
        {
            $zip->extractTo('path');
            $zip->close();
        }

if lib folder is already exist in the directory where we are unzipping then except lib(folder) all other files and folders should get override.
