Nomad PHPSymfony Social Stats (19.1.2017, 19:16 UTC)

Recently my good friend Ryan Weaver of KNPLabs released a very interesting page of statistics for the Symfony framework. The page titled “Symfony Trends” shows pretty graphics of some of the non-traditional statistics. Most of the time when we look at framework stats they are things like page load time and pages per second, the …

Matthias NobackIntroducing the SymfonyConsoleForm package (19.1.2017, 12:10 UTC)

About 2 years ago I created a package that combines the power of two famous Symfony components: the Form component and the Console component. In short: this package allows you to interactively fill in a form by typing in the answers at the CLI. When I started working on it, this seemed like a pretty far-fetched idea. However, it made a lot of sense to me in terms of a ports & adapters architecture that I was looking for back then (and still always am, by the way). We could (and often should) write the code in our application layer in such a way that it doesn't make a big difference whether we call applications services from a web controller or from a CLI "controller".

As described by Bernhard Schüssek (author of the Symfony Form component) in his article Symfony2 Form Architecture, the Form component strictly separates model and view responsibilities. It also makes a clear distinction between processing a form and rendering it (e.g. in an HTML template). If you're familiar with Symfony forms, you already know this. You first define the structure and behavior of a form, then you convert it to a view (which is basically a DTO). This simple data structure is used to render HTML.

This strict separation of concerns has brought us a well-designed, yet fairly complicated form component. In my quest for "console forms", this was a great gift: it was actually quite easy to render form fields to the terminal output, instead of to an HTTP response.

I decided to rely on the existing Question Helper which allows console commands to ask questions to the user. This basically left me with the need for "bridging the gap" between the Form and Console component. This is a quick list of things I needed to fix:

  • Different form fields require different console question types. A choice type form field matches more or less with a ChoiceQuestion. But since the mapping isn't one-to-one, I introduced the concept of a FormToQuestionResolver which configures a Question object in such a way that the user experience matches to that of a web form field. For example: a password type form field gets transformed into a Question with hidden output.
  • It's relatively easy to ask single questions (e.g. "Your name: "), but it was a bit harder to ask for "collections", like "Phone number 1: ", "Phone number 2: ", etc.). I fixed this by introducing something called a FormInteractor which gets asked to arrange any number of user interactions that are required to fill in the form.
  • CSRF tokens aren't needed for console commands, so CSRF protection will automatically be disabled.
  • In some places this package relies on behaviors of the Form and Console component that are not covered by the Symfony Backwards Compatibility Promise. This means that for every minor release the package is bound to break for some (often obscure) reason. I have kept up with Symfony 2.8, 3.0, 3.1 and 3.2, but if things get too hard to maintain, I will consider dropping some versions.

A short list of changes in external libraries that have been causing trouble so far (I'm by no means criticizing the Symfony development team for this, it just might be interesting to share this with you):

  • The behavior of a ChoiceQuestion changed at some point, switching what was returned as the selected value (instead of the selected "key" at some point it started returning the selected "label" of a choice). See also my custom solution, AlwaysReturnKeyOfChoiceQuestion. Furthermore, around the same time the Form component switched the behavior of its ChoiceType form type, accepting an array of "label" => "data" value pairs, where I was used to providing the exact opposite (an array of "data" => "label" pairs).
  • Of course, there was the major overhaul of the form type system, where form types changed to being fully-qualified class names instead of simple names. I wanted to keep supporting both styles, so this took some time to get right. At some point, t

(No, not really porn. Totally SFW)  Today Taylor Ottwell, creator of the Laravel framework, posted the Framework Code Complexity Comparison. For those not familiar with “Cyclomatic Complexity” here’s the Wikipedia page Cyclomatic Complexity. Briefly, “Cyclomatic Complexity is a software metric (measurement), used to indicate the complexity of a program.” While Taylor’s post gives you the …

Rob AllenHomestead per-project crib sheet (18.1.2017, 12:33 UTC)

I wanted a drop-dead simple way to try and replicate a problem someone was having on the Slim forums. I couldn't reproduce with php -S which is my go-to for this sort of thing, so I thought I'd try Homestead.

I had recently listend to a Voices of the Elephpant episode with Taylor Otwell & Joe Ferguson where Joe mentioned that Homestead worked on a per-project basis too. I didn't know this, so tried it out. The docs are fine, but there's a lot there that covers the global installation option when I just want to get up and running on a per-project basis.This is my crib sheet:

1. Create project

$ composer create-project slim/slim-skeleton skelly
$ cd skelly

We just need a project that uses Composer. You probably have one already. If not, Slim Framework is a good choice!

2. Add Homestead to the project

$ composer require laravel/homestead --dev
$ php vendor/bin/homestead make

The make command creates VagrantFile and a Homestead.yaml for configuration.

3. Deal with IP address and hostname

By default, the Homestead vagrant box is set up on 192.168.10.10 with the hostname homestead.app. You can change this in Homestead.yaml.

Add the IP address to /etc/hosts. This only needs to be done once if you don't change the defaults.

$ echo "192.168.10.10 homestead.app" | sudo tee -a /etc/hosts

All done

We're all done, so we can use vagrant up to run our new website Go to homestead.app in a browser to see it. To shut down, use vagrant halt or vagrant destroy.

PHP ClassesSimple Tutorial on using MySQL with PDO that works with PHP 7 (18.1.2017, 09:11 UTC)
By mohammad anzawi
Most PHP applications use MySQL databases but since PHP 7 was introduced the old MySQL extension was discontinued. Developers need to migrate either to using MySQLi or PDO.

Using PDO makes your code usable also with other types of databases besides MySQL.

Read this tutorial to learn how to perform simple common database queries as well perform table schema management operations using the PHP PDO database class.
