版本:CodeIgniter_2.0.1

希望CI 应用的URL不包含index.php
例如: http://www.example.com/index.php/product/712
希望变成这样http://www.example.com/product/712
这样url更漂亮,也许这样seo更友好,通过urlrewrite就可以实现

只需用下面3个步骤就可以搞定:
1.建立.htaccess写入重写规则如下
[code]
<IfModule mod_rewrite.c>
??? RewriteEngine On
??? RewriteBase /

??? #Removes access to the system folder by users.
??? #Additionally this will allow you to create a System.php controller,
??? #previously this would not have been possible.
??? #'system' can be replaced if you have renamed your system folder.
??? RewriteCond %{REQUEST_URI} ^system.*
??? RewriteRule ^(.*)$ /index.php?/$1 [L]
???
??? #When your application folder isn't in the system folder
??? #This snippet prevents user access to the application folder
??? #Submitted by: Fabdrol
??? #Rename 'application' to your applications folder name.
??? RewriteCond %{REQUEST_URI} ^application.*
??? RewriteRule ^(.*)$ /index.php?/$1 [L]

??? #Checks to see if the user is attempting to access a valid file,
??? #such as an image or css document, if this isn't true it sends the
??? #request to index.php
??? RewriteCond %{REQUEST_FILENAME} !-f
??? RewriteCond %{REQUEST_FILENAME} !-d
??? RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
??? # If we don't have mod_rewrite installed, all 404's
??? # can be sent to index.php, and everything works as normal.
??? # Submitted by: ElliotHaughin

??? ErrorDocument 404 /index.php
</IfModule>?
[/code]

2.设置$config['index_page']为空置
打开文件system/application/config/config.php把代码
[php]$config['index_page'] = "index.php";[/php]
改为
[php]$config['index_page'] = '';[/php]

3.确保apache支持url重写,重启apache
