Modern PHP, soft skills, productivity and time management.
If you’re refactoring something – do it iteratively.
Recently I was refactoring some code, it was time to pay off some debt. We have modular monolith and it appeared that one module was clearly a part of another, they just ping-ponged themselves all the time.
I was convinced that it was trivial. Communication from and to the module is done entirely via the module’s API. So it’s enough to move all files from the obsolete module to the other one and done. Right?

I remember that I saw arrow functions in js for the first time. It was pretty hard to understand for me, but I didn’t do anything in js in years, so I just get used to this unknown.
But recently I’m working in a project with PHP 7.4. And guess what. Yup, arrow functions arrived in PHP in exactly this version. So I hadn’t a choice but to sit down and understand this little bastard.
Arrow functions in PHP are fairly simple, yet quite nice, and a little different than ordinary lambda functions.

I’m a Symfony guy, but from some time I have to use Laravel. There is the neverending war between those, but what do. It’s not that bad eventually…
Recently I was supposed to add logs to some command, for debugging purpose. Laravel has its logger as facade but I didn’t want to use this one, I just wanted to log some data to separate log file, debug the command and delete the log. And there is no way I found to create a separate log by using the `Log` facade.
As it turns out, Laravel’s log facade uses monolog, so there is a possibility to access monolog itself and create a new logger. I’ve searched the web for the best solution, some suggest creating a new facade and using it, some suggests creating logger “in place” and use it only in my command. But none of it seems right…

If you want to deploy Symfony app using Capistrano 3 to cheap OVH VPS then you’ll need to write a simple task to set proper permissions.
Edit: unfortunately, there was still a little problem with permissions and I made deployment semi-automatic.
I have a very cheap VPS in OVH, it costs only about $2 per month. It is perfect for my needs, I have my blog there, I have my friend’s blog as well. And now I want to move my wife’s portfolio from (even cheaper :P) shared hosting to this VPS.
Until now deploy to shared hosting looked like this:
Nightmare.
Fortunately, I had access to SSH on my hosting (not popular thing) so I could try to automate this process a little bit. But because I already have VPS then the better idea was to move the portfolio there and use some tool for deployment.
The portfolio is written using Symfony 2 framework so the best idea is to use Capistrano. I had some experience with Capifony which is pretty old, unmaintained customization for Capistrano 2 (which is also quite old). I don’t want to use old stuff. So the goal is easy: deploy Symfony 2 app using Capistrano 3 to OVH, cheap VPS.

If you’re writing commands in Symfony then you probably know the ProgressBar component. It’s useful tool showing the current state of operations and, more importantly, ETA and used memory. Cool.
If you’ll go to the official ProgressBar component page then at the beginning you’ll see a very cool progress bar, with colors, icons, changing status messages, but… If you’ll look a little further you’ll see a sad, black and white progress bar, that is far from a “promise” made at the beginning 🙁
Heads up! We’ll make it like this 🙂

I wanted to write a manual about installing PHP5.6 and PHP7.1 at the same time, on OS X, using homebrew instead of using Docker (which I find not the best idea on OS X, but maybe I’m wrong?). But someone did it before me 🙂
If you want to have many PHP versions simultaneously then follow the instructions described by Jani Tarvainen on Symfony Finland blog: https://symfony.fi/page/how-to-run-both-php-5-6-and-php-7-x-with-homebrew-on-os-x-with-php-fpm and enjoy native, fast and simple way to work on crappy old projects in PHP5.x and new, shiny ones in 7.1 😛

This is a simple tutorial how to set up Selenium test with PHPUnit and phantomjs for easy and fast testing.
Today I wanted to learn something about Selenium. It’s very popular testing tool for any application that can be launched using a web browser, regardless of programming language or technology. I don’t know it very much, in fact, I know only how to set it up and write the simplest test 😉 But I want to share my today’s experiences because I cannot find any simple tutorial and had to glue together scripts, setting and libraries from all across the internet 😉
If you don’t like reading tutorials and want rather dig into example code I created the repository on GitHub where you can find everything I talk about here.

This blog post will contain useful information for those, who want to start developing in Symfony without setting up a server (like apache or nginx) or installing docker.
PHP from version 5.4 has built in server. You can run it by executing in console php -S 127.0.0.1:8000 in your projects directory. When you go to this address (of course you can change the port and 127.0.0.1 to localhost) you’ll see the main page of your project.
I was challenged in my last post to deeper check performance of strings. I think it will be quite interesting to test out some cases and say which way of using strings is the best.
In this post, I will check several string usages in PHP 5.6 and PHP 7.
To simplify testing I created a simple function which gets 2 arguments: an array of callable functions to compare (as many as you want) with names to display in summary, and a number of loops to test the function…

As you may know, in PHP you can use single and double quotes for strings. These two lines are equal:
<?php $str1 = "some string"; $str2 = 'some string'; // $str1 === $str2 returns true
The only difference here is handling variables placed inside quotes. Let’s look at this simple example:
<?php $name = "John"; $str1 = "Hello there $name"; $str2 = 'Hello there $name'; echo $str1; // gives Hello there John echo $str2; // gives Hello there $name
As you can see in double quotes variables are processed and in single quotes they aren’t.
But which one should I use?
