## Features
* Support for Apache and the PHP built-in webserver
* Tested
* No dependencies
* Very fast
### Supported servers
* Apache webserver with mod_rewrite and .htaccess
* PHP build-in webserver
## Requirements
* PHP 7.2+ or 8.1+
## Installation
```
composer require selective/basepath
```
The recommended **directory structure**:
* `public/` Web server files, the [DocumentRoot](https://httpd.apache.org/docs/2.4/de/mod/core.html#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:
```htaccess
# 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:
```htaccess
RewriteEngine on
RewriteRule ^$ public/ [L]
RewriteRule (.*) public/$1 [L]
```
## Usage
### Slim 4 integration
Add the `BasePathMiddleware` after `addRoutingMiddleware()` to set the basePath before
the routing is started.
Example: `public/index.php`
```php
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();
```
### Apache usage
* 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!`.
### PHP built-in webserver usage
* 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!`.
### Good URLs
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`
### Retrieving the base path
```php
$basePath = \Slim\Routing\RouteContext::fromRequest($request)->getBasePath();
```
### Creating a relative url with the base path
```php
$routeParser = \Slim\Routing\RouteContext::fromRequest($request)->getRouteParser();
$url = $routeParser->urlFor('root');
```
### Rendering the base path into a Twig layout template
This example requires [slim/twig-view](https://github.com/slimphp/Twig-View)
```twig
{% block content %}{% endblock %}
