的.htaccess只​​允许访问并重定向到根的index.php只为一个目录

我得到一些麻烦与htaccess的在我的新的PHP项目。所以我想问在这里，希望有人可以帮助我走出我找不到任何解决方案。

I'm getting some troubles with htaccess in my new php project . I couldn't find any solutions so I ask here , hope someone will help me out.

1。我需要什么：

在根，指向现有的文件和文件夹的网址不能访问，除/公共/及其所有文件夹和文件（只/公共/被允许访问）。网址指向的文件和文件夹，这是不existings将被重定向到根的index.php 。 /公共/重定向到根的index.php 太，文件夹和文件里面都没有（直接访问）。

On root , urls pointing to existing files and folders are not accessible , except /Public/ and all its folders and files ( only /Public/ is allowed to access ) . Urls pointing to files and folders which are not existings will be redirected to root index.php. /Public/ is redirected to root index.php too , folders and files inside it are not ( direct access ).

2。我曾尝试和不工作：
