apache rewrite index.php 去除

在php编程框架里很多都有index.php这个，apache可以通过 在项目目录下 编辑 .htaccess文件 来隐藏index.php。但我一直失败，后来在stackoverflow里看到有人提出一个方法，修改apache的httpd.conf文件。

All above methods failed for me and then I found that I was not changing AllowOverride None toAllowOverride All in my virtual host file at /etc/apache2/sites-available/default

<VirtualHost *:80>
    ServerAdmin webmaster@localhost

    DocumentRoot /var/www
    <Directory/>
            Options FollowSymLinks
            AllowOverride All    <---- replace None with All
    </Directory><Directory/var/www>
            Options Indexes FollowSymLinks MultiViews
            AllowOverride All   <---  replace None with All
            Order allow,deny
            allow from all
    </Directory>
