Fast Web Scraping With ReactPHP: Download All Images From a Website
Have you ever needed to grab some data from a site that doesn’t provide a public API? To solve this problem we can use web scraping and pull the required information out from the HTML. Of course, we can manually extract the required data from a website, but this process can become very tedious. So, it will be more efficient to automate it via the scraper.
Well, in this tutorial we are going to scrap cats images from Pexels. This website provides high quality and completely free stock photos. They have a public API but it has a limit of 200 requests per hour.

How to Improve Your Debugging Skills
All of us write code that breaks at some point. That is part of the development process. When you run into an error, you may feel that you don’t know what to do. However, even the most seasoned developers introduce errors and bugs that break their code. We are humans after all.

DDD, Hexagonal, Onion, Clean, CQRS, … How I put it all together
Fundamental blocks of the system
I start by recalling EBI and Ports & Adapters architectures. Both of them make an explicit separation of what code is internal to the application, what is external, and what is used for connecting internal and external code.

Dynamic relationships in Laravel using subqueries
Developers are typically pretty good at the first goal. We're aware of N+1 style problems, and use techniques like eager-loading to limit database queries. However, we're not always the best at the second goal—keeping memory usage down. In fact, we sometimes do more harm than good trying to reduce database queries at the expense of memory usage.
Let me explain how this happens, and what you can do to satisfy both goals in your app.

Laravel features you may not know about
Here are some features from Laravel that you may not be aware of. They're not exactly anything advanced or hidden, but I don't really notice that these functions get used or referenced very often. (Maybe they are though, and I've just not noticed it.)

PSR-18: The PHP standard for HTTP clients
A couple of days ago, the PHP Framework Interoperability Group (PHP-FIG) approved the PSR-18 “HTTP Client” standard. This standard was the last missing piece to build applications that need to send HTTP requests to a server in an HTTP client agnostic way.

Migrating to password_verify
I’ve recently been updating a website that was written a long time ago that has not been touched in a meaningful way in many years. In addition to the actual work I was asked to do, I took the opportunity to update the password hashing routines.

Good Engineering Practices while Working Solo
When you’ve got to go it alone, how do you make the most out of it?
Most developers work as part of a team. However, at some point in our careers, we’ve had to (or we’ll have to) work alone. And while much of product development involves being able to manage or work with the rest of the team, it’s equally as important to develop good practices while working solo.
