Four steps are required to enable Yii's URL rewriting. First, set the urlManager in the configuration file, enablePrettyUrl and hide index.php; secondly, if you use Apache, you need to configure the .htaccess file to enable URL rewriting; thirdly, if you use Nginx, you need to modify the server block configuration to correctly forward the request; finally, test and verify whether index.php is successfully removed and access is normal.
Enabling URL rewriting in Yii is a straightforward process, but it can trip you up if you miss one or two steps. The main goal is to make URLs cleaner and more user-friendly by removing index.php from the URL.
1. Configure urlManager in Yii config
The first step is to adjust the URL manager settings in your Yii configuration file ( config/web.php for Yii2 basic or advanced template).
You'll want to set 'urlFormat' => 'path' and enable 'enablePrettyUrl' => true . Here's what that part of your config should look like:
'components' => [
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' => [
// your custom rules go here
],
],
],-
enablePrettyUrlturns on pretty URLs. -
showScriptNameset tofalsehidesindex.phpfrom the URL. -
rulesis where you define custom routes later on.
If you skip this step or misconfigure it, your URLs will still work but won't be clean.
2. Set up .htaccess for Apache
If you're using Apache , you need an .htaccess file in your web root (usually the web/ folder in Yii2 projects) to rewrite URLs properly.
Here's a standard .htaccess content:
RewriteEngine on
# If a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Otherwise forward it to index.php
RewriteRule . index.php This tells Apache to route all requests to index.php , unless the file or folder actually exists (like images, CSS, JS, etc.). Without this, even with the config changes, your site will return 404s when trying to access clean URLs.
Make sure mod_rewrite is enabled in Apache. You can check this by looking at your Apache config or running a2enmod rewrite on Linux systems.
3. Nginx users: update server block config
If you're using Nginx , you don't rely on .htaccess . Instead, you need to modify your Nginx server block configuration.
Here's a typical setup:
server {
listen 80;
server_name example.com;
root /path/to/your/yii2/web/;
index index.php index.html;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php-fpm.sock;
}
} This makes sure any request not matching an actual file gets sent to index.php , which Yii uses to handle routing. If you skip this, you'll get 404 errors again, even though everything else seems configured right.
4. Test it out
Once you've made both config changes — in urlManager and either .htaccess or Nginx config — restart your server (if needed), then try visiting a page on your site without index.php in the URL.
For example:
- Before:
http://example.com/index.php?r=site/about - After:
http://example.com/site/about
If it works, great! If not, double-check:
- That
urlManagersettings are correct. - That
.htaccessor Nginx config is properly applied. - That
mod_rewriteis enabled (for Apache). - That your server has permission to read
.htaccess.
It's not complicated, but there are enough moving parts that missing one thing can break the whole setup.
