A URL base path detector for Slim 4.
- Support for Apache and the PHP built-in webserver
- Tested
- No dependencies
- Very fast
- Apache webserver with mod_rewrite and .htaccess
- PHP build-in webserver
- PHP 8.2 - 8.5
composer require selective/basepath
The recommended directory structure:
- public/ Web server files, the DocumentRoot
- .htaccess Apache redirect rules for the front controller
- index.php The front controller
- .htaccess Internal redirect to the public/ directory
The following steps are necessary for your Slim 4 application:
For Apache we have to "redirect" the web traffic to the front controller in public/index.php.
Create a file: public/.htaccess with this content:
# Redirect to front controller
RewriteEngine On
# RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]
We also need a rule to "redirect" the sub-directories to the front-controller in public/index.php.
Create a second .htaccess file above the public/ directory with this content:
RewriteEngine on
RewriteRule ^$ public/ [L]
RewriteRule (.*) public/$1 [L]
Add the BasePathMiddleware after addRoutingMiddleware() to set the basePath before the routing is started.
Example: public/index.php
<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Selective\BasePath\BasePathMiddleware;
use Slim\Factory\AppFactory;
require_once __DIR__ . '/../vendor/autoload.php';
$app = AppFactory::create();
// Add Slim routing middleware
$app->addRoutingMiddleware();
// Set the base path to run the app in a subdirectory.
// This path is used in urlFor().
$app->add(new BasePathMiddleware($app));
$app->addErrorMiddleware(true, true, true);
// Define app routes
$app->get('/', function (Request $request, Response $response) {
$response->getBody()->write('Hello, World!');
return $response;
})->setName('root');
// Run app
$app->run();- Start the apache webserver
- Open your website, e.g. http://localhost or http://localhost/{my-sub-directory} and you should see the message Hello, World!.
- Open the console and change into the project public/ directory. Then run:
php -S localhost:8000
If you don't start the webserver from the project public/ directory, you have start it with a specific document root directory:
php -S localhost:8000 -t public
- Open http://localhost:8000 and you should see the message Hello, World!.
The public/ directory is only the DocumentRoot of your webserver, but it's never part of your base path and the official url.
Good URLs:
- https://www.example.com
- https://www.example.com/users
- https://www.example.com/my-app
- https://www.example.com/my-app/users
Bad URLs:
- https://www.example.com/public
- https://www.example.com/public/users
- https://www.example.com/my-app/public
- https://www.example.com/my-app/public/users
$basePath = \Slim\Routing\RouteContext::fromRequest($request)->getBasePath();$routeParser = \Slim\Routing\RouteContext::fromRequest($request)->getRouteParser();
$url = $routeParser->urlFor('root');This example requires slim/twig-view
