We create a custom response about, set an header that will set the encoding of our pages to utf-8 and then pass that response object to the frontcontroller. But wait, we just introduced two new things, the frontController and the resource plugins. Let's start with the frontController. The frontController handles a lot of stuff for us, so we don't have to bother. In an MVC environment like ours, the frontController holds the request object.
It sends the request to an action depending on the defined routes. If the frontController does not find the action defined by the routes or if there is an error in the action itself then it will call the errorHandler plugin. Finally it takes the response object and passes it to the viewRenderer so that the data can be send the data back to the user as an html page. At every step of the frontController emits events. We will see later that you can listen to those events with plugins. So our plugins could modify the request before it reaches an action or for example modify a response after the action has been executed.
The resource plugins are a new feature that got introduced in ZF 1. It allows you to reduce the amount of code in the bootstrap by putting resources code into plugins instead of having all the code in the bootstrap. The other advantage of the resource plugins is that they can be reused and shared between multiple apps.
You can also find more information about the available resources in the resources documentation. Of course you can also write your own resources. To get an instance of a bootstrap resource plugin just call the getResource method of the bootstrap object. To configure resources open your application. We now setup our logger, to log errors and other information. We use the Zend Framework log stream write component.

Here we tell the logging component that we want to write our messages in a file called application. Instead of writing log messages into a file we could also send them to firebug using the firebug writer.
In this part we set the encoding of our html views to utf-8 or use another encoding, but it should be the same you used for the response when initializing the frontcontroller. As doctype we use html5 because for the layout we will use html5 markup. Some PHP frameworks prefer conventions over configuration concept, where most of your parameters are hard-coded and do not require configuration.
This makes it faster to develop the application, but makes it less customizable. In Zend Framework 3, the configuration over conventions concept is used, so you can customize any aspect of your application, but have to spend some time for learning how to do that. Let's look at this subdirectory in more details figure 3. Figure 3. Configuration files. It is used by the application on start up for determining which application modules should be loaded and which services to create by default. Below, the content of application. You can see that the configuration file is just a usual PHP nested associative array, and each component may have a specific key in that array.
You can provide inline comments for the array keys to make it easier for others to understand what each key means. In line 3 we have the modules key defining which modules will be loaded on start up. You can see that the module names are stored inside of another config file modules. Summing up, you typically use the main application.
In this file you can also tune the service manager.

It is not recommended to add more keys in this file. And let's also look inside the modules. Currently, you have the following modules installed in your website:. The Application module is a module containing your app's files.

All other modules listed are Zend Framework components. In ZF3, a special Composer plugin called component installer was introduced. And the installer injected those components' module names here, in modules. These config files are automatically loaded and recursively merged with the module-provided config files, that's why their directory is named autoload. Here are some hints:.
For example, here you can store parameters which override the default parameters of some module. For example, here you can store your database credentials. Each developer usually has a local database when developing and testing the website. The developer thus will edit the local.

When you install your site to the production server, you will edit the local. Each developer in your team then renames the local. This local. If you remember, we enabled the development mode earlier in the Zend Skeleton Application chapter. The development.
