After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package router

Hengeb\Router

a PHP router that makes use of attributes and provides autowiring

example usage

Make sure your HTTP server redirects alle requests to index.php (the front controller).

example nginx directive:

In index.php, create the Router object and dispatch the request:

The router will look for a controller with a Route attribute that matches the router. The router will cache the routes and only re-analyze the controllers when a file has changed.

Model injection

You can tell the Router object how to retrieve an object of a given type:

The third parameter is optional. Use it if there are multiple ways to find the target.

Alternatively your model can implement the RetrievabelModel interface that is part of this package.

Request value injection

You can use the RequestValue attribute to inject a request value (POST or PUT).

Service injection

You can tell the Router how to retrieve a service object:

Or using a closure so objects will only be created when they are needed:

Or the Router object will try to find the service automatically, either by calling $className::getInstance() or by creating a new object (with service injection in the constructor, be careful so you don't end up in endless recursion)

Exception handling

If something goes wrong a default error page will be shown with a short description of the error and the according HTTP status code.

You can add a method handleException(\Exception $e, ...) (other dependcies will be injected) to your controller to handle the exception.

However, this will not work if no controller could be determined because no route matches request. To cover this case you can add a custom exception handler:

The class will be created with service injection.

Alternatively you can use a closure:
