php - Is there a way to get this by .htaccess file? -

in site root directory. there donghua.php , index.php. now, there way use .htaccess file let visitor access site .the default shows example.com/donghua.php. not example.com/index.php. thank you. server apache.

ps:the user still can access example.com/index.php

i using directoryindex donghua.php in .htaccess. default page ok. when access example.com/index.php redirect example.com/donghua.php. if forbid redirect how do?

if have access virtual host config file (or should able in htaccess) can set directoryindex donghua.php if want, i.e. instead of this:

directoryindex index.html index.php default.html 

just do:

directoryindex donghua.php 

so whenever goes website, example.com, apache installation read donghua.php default index file.
