CodeIgniter关于www.CNAME和index.php的URL/URI

我目前在.htaccess中有以下内容：

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]

RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

当我键入不带www前缀的域名时：

[我在URL栏中键入的内容=>它最终会变成什么]

example.com => http://www.example.com/ == GOOD!

如果我输入：

www.example.com/register => http://www.example.com/register == GOOD!

example.com/register => http://www.example.com/index.php/register == BAD!

但当我输入时：

www.example.com/register => http://www.example.com/register == GOOD!

example.com/register => http://www.example.com/index.php/register == BAD!

如何删除所有角落案例的index.php部分？特别是最后一个…

请尝试此代码

# First add the www to URL
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]

# The remove the index.php from URL
RewriteCond $1 !^(index\.php|ref_doc|media|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

我想订货很重要
