if($_FILES){

    foreach($_FILES as $key=>$val){
        if(!empty($val['tmp_name'])){
            $ext = end(explode(".",strtolower(basename($val['name']))));
            if(in_array($ext,$allowedExtensions)){
                $file = 'PATH_TO_UPLOAD'.basename($val['name']);

                if(move_uploaded_file($val['tmp_name'],$file)){
                    //SUCCESS_MESSAGE
                }
            }else{
                //FAIL_MESSAGE
            }
