Last month I had the pleasure of achieving my first full year as a professional web developer in a Finnish company centered around online payments.
My background includes a couple of years as a technical service desk employee in a large ISP, university studies centered around digital game design, and some pop-culture criticism to blogs and hobbyist papers.
I'm 30 years old and currently writing a Master's thesis about playtesting. Let this be my introductory post for the dev.to community and my personal retrospective on three important things I've learned this year.
#1 PHP Is Back With a Bang
Or depending on your point of view, still great. That is an acceptable answer too. I used to make some simple dynamic websites and customize WordPress blogs with PHP 5 and quickly saw myself growing tired of it. Languages like Python and Ruby just felt a lot more sensible and fun to design websites with than old dog PHP. Luckily, that is not the case anymore.
In the university information system class my software engineering teacher – who happens to also be a professor – referred to PHP as a toy language which nobody should use. I'm sure many of you have read at least one of those notorious blog posts warning about PHP being bad in everything but in
2017++ that is actually very far from the truth.
PHP of today comes with strict typing, great local development support with Vagrant and Docker, smarter syntax (never type
array() again), and a ton of handy frameworks. Speaking of frameworks, use them. Seriously. Not only do frameworks like Laravel and Lumen enhance your application security, they also provide you with a huge array of helpers from database abstractions, authentication patterns and to – one of my favorites – templating engines. You'll still get funny comparisons like:
echo 123 == '123lol' ? 'True' : 'False'; # Outputs True
But that will just teach you to compare types besides values. Switch
=== above and see what happens.
All the goodness of frameworks also concerns CMS platforms like WordPress as well. For example, Sage 9 is an upcoming major update to the popular WordPress starter theme that allows you to write your theme using Webpack, Blade templates and Bootstrap 4.
A matter of past are the days you had to edit your PHP files locally, then fire up an FTP client like FileZilla or WinSCP for transferring your code to a remote server, and finally hope that everything works. My personal PHP workflow consists of installing PHP locally via Homebrew package manager, setting up nginx, MariaDB, Redis, and other dependencies inside their own Docker containers that I've linked together with Docker Compose. I could as well install all of these in a virtual Vagrant box like Homestead or Scotch or just let them live happily in macOS environment. However, this is the approach I'm most comfortable with and it gives enough freedom when moving between laptops.
In short, PHP gives you freedom while not sacrificing current best practices. It's fine not to like it, but only if you've understood the facts and not jumped on some random hater bandwagon.
#2 Don't Be a Fool, Configure Your Tools
This is very an important topic which often gets overlooked. Setting up your environment is and should be more than just downloading a basic text editor like Sublime Text and enabling syntax highlighting. If you're a Vim user you understand editor configuration like no one else does.
I'm in a lucky position where my manager actually allows and recommends us to educate ourselves and explore better workflows when there are no critical issues waiting on board. To that end, I've been consuming Laracasts videos about tooling which I recommend to everyone.
So, pick your weapon of choice, explore its features and limitations as long as it takes. Then set it up with your favorite UI scheme and install the necessary plugins. Do this before starting to write the first line of code to that groundbreaking new app you're working on.
I, not unlike many others, have switched from alternating between Vim and Atom to Visual Studio Code which already gives me integrated terminal, debugging, unit test runner, and some intelligent static analysis and code refactoring tools via extensions. For some of the more advanced tasks, I still use IntelliJ IDEA which currently has better PHP integration but I plan to start using VS Code as my only editor as soon as possible.
Despite Linus Torvalds badmouthing the use of debuggers I strongly advise using one – XDebug is good for PHP. Without a debugger, you'll place an additional cognitive load on your brain while trying to keep the flow of system in your mind. It is then very likely you just get tired and start dumping the shit out of every variable in scope to your files until you find the poor sucker method returning
127 instead of
false. With a debugger, you see the entire state of the application as it is until the breakpoint, and you can evaluate expressions inside that state. Not only does it save time but blocks needless fatigue as well.
As a last but not least important bit of advice; if someone likes Emacs do not try to religiously convert them to use Vim or vice versa. You just look like you left your brain in the previous century. The culture around development tools is vastly rich and everyone has space for choosing their best equipment. Or would you start arguing with Gimli to switch his ax for a bow right before a horde of Uruk-hai is preparing for attack? I don't think you would.
#3 Continuous Integration Guarantees Sweet Dreams
If you don't know what continuous integration (CI) means it has been explained in detail in this post.
We, like any decent software company, do code reviews as part of our development process. Without a stable CI, we would be drowning in regression bugs and would need to bug our colleagues if they have tested this or that and with what coverage.
In my primary project we have set the CI to first run code linting with PHP Code Sniffer and PHP Mess Detector (which are wonderful tools when configured right), run unit tests with coverage, and ultimately check if the coverage is 100 %. Any previous check returning non-zero exit code will fail the run and alert the developer through a notification. Lower than full coverage will also fail the run. If any of the checks have failed we do not approve the code review. At times it's a difficult way but it ensures the technical debt stays relatively short, code quality stays on acceptable levels, and new features will not break existing ones.
CI is also fairly easy to set up in Travis and in Gitlab with a couple of YAML blocks. If you work on a project with more than a handful of developers using CI is well worth it if not mandatory.
2018 will see me developing these skills even further while adopting some new ones. Now I'm interested in hearing what were your special lessons from your first year?

If you like Laravel and all the environment it comes with, give Symfony a try. This project gave so much to the PHP ecosystem and just released a new major update to its framework. For example: composer has its roots up there as well as many libs used in Drupal, Laravel and many other projects.
Yes, at some point I'll have to. I started my PHP path (after basics, of course) with Zend Framework back in the day but Laravel has been the home for me. I've also been recommended to try out CodeIgniter.
