Thank you for you advice. But could you elaborate about the technical insight? The author has also made Advanced Explorer, a JavaScript + Node.js version of a file manager previously written in Java, so he has some knowledge on the topic.
It would probably help if you had experience on both sides - as the comment suggests, the author doesn't seem to have much insight into how PHP works: "PHP also allows you to link libraries written in C, but we must recompile the interpreter with the appropriate options".
It reads like someone who isn't a native English speaker (not a bad thing, their grammar is very good, but the cadence isn't quite natural), and the design screams "content farm", which makes you perceive the writing style negatively. It's not a great article, but the context makes it look even worse.
