get all files and serialize to array

i want to get all files list and serialize to array, example:

---

"list" => array("filename", "filename", "filename", "filename");

---

Thanks in advance.

if(Input::hasFile("rows")) {
    foreach(Input::file('rows') as $file){
        $format = serialize(array(
            "list" => array($file->getClientOriginalName()) // list of all files
        ));
    }
}
