在config.php

$config['uri_protocol']    = 'REQUEST_URI';
 $config['index_page'] = '';

在项目位置创建.htaccess文件，其中包含以下内容（例如：/var/www/html/yourproject create .htaccess inside 'yourproject' folder）

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

将以下内容添加到虚拟主机配置文件中

<Directory "/var/www/html/yourproject">
            Options All
            AllowOverride All
            Allow from all
</Directorey>

然后重新启动Apache

按照以下步骤从url中删除index.php
1)从config.php文件中删除“index.php”

$config['index_page'] = "";

2)你的.htaccess文件应该是：

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [L]

3)在某些情况下，您还必须在配置文件中更改此设置

//find the below code
$config['uri_protocol'] = "AUTO"
//replace with the below code
$config['uri_protocol'] = "REQUEST_URI"

只需在.htaccess文件中使用它

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

<IfModule !mod_rewrite.c>

    ErrorDocument 404 /index.php
</IfModule>
