I have curated some fantastic reads for you this week. Let’s get to them!
Managing Your WordPress Site With Git and Composer
By: Ross Wintle
These are 2 programs that I absolutely have to step up my game with. I know there is more to Git than
git pull and
git push. Same with Composer.
This article covers managing WordPress with both Git and Composer.
I really like these 2 passages from the article:
"Version control systems like Git are a huge help to developers, allowing collaboration on a level that wouldn’t be possible without them."
"Version control gives you the freedom to experiment, while always leaving you with the option of turning back the clock if you don’t like the results."
This is a meaty article so bookmark and reference as needed.
Linux su vs sudo: what's the difference?
By: David Both
I've used both of these commands at various times across my many personal Linux installs and never really knew the difference between them. I know they both get the job done (authentication in a sense for users lacking the privileges).
As it turns out, there is a difference between
sudo and this article explains it well.
Here is a fly-by look:
sudo- more temporary time access to needed privileges.
su- no time constraints on the escalated privilege level.
Understanding MySQL Joins
By: Neeraj Kushwsha
We have to use JOINs in SQL. There really is no way around it when working with a normalized database and the data is spread across multiple tables.
Many times, it comes down to using the correct
JOIN type in order to get all the right data for a particular query.
This article shares examples of the 3 MySQL
My favorite Laravel development environment, with Docker, Nginx, PHP-FPM Xdebug in VSCode
Here is a fantastic article for Laravel developers looking for a detailed plan to set up a sound development environment. I've not personally used any of this software, so they're all new to me.
However, I can see the benefits of having a reproducible (or familiar at the very least) dev environment and definitely want to settle on one of my own someday.
SRP: Single Responsibility Principle
By: Ben Kachoud
The Single Responsibility Principle is the first in the SOLID Design Principles for Object Oriented Programming (OOP) and says every class should have a single responsibility.
In this article, we see an example in PHP of how to implement the Single Responsibility Principle for a shopping cart type of implementation.
Understanding PHP Operators of Logic, or || and && and ! a lot more
By: David Hayes
Boolean logic controls application flow and is essential in both understanding and implementation.
While the examples in this article are in WordPress, the overarching concept is not WordPress-specific.
I absolutely love this passage from the article:
"At the risk of oversimplifying, in WordPress we simply store specific data, and then build simple little machine (called “WordPress themes”) to display that data to specific people in specific way under specific conditions."
Replace Nested If Else Statement with Array
By: Tim Oye
I know I've written some ugly nested
else statements myself. In this article, the author covers using arrays and returning early to mitigate having many nested
The null coalescing operator (
??) is used as well and it is such a handy PHP operator.
