The class content is good.. but I wonder if they prepare it.. When explaining functions or logic, why? and how to use it are things that beginners desperately want... Oh my.. I took off 1 point because I skipped over it too quickly. Also, when I skipped around, my pronunciation was slurred a lot, so it was hard to understand. The reason students pay to take the class is because they want to know why functions are used.. how the logic works, but there are almost no cases where they are taught.. Since there aren't many video lectures related to PHP controllers right now, if you have to watch this, I recommend this lecture. :) Please... If it's because of the pronunciation, please put subtitles on it.. Ah! It's good to leave comments.. Of course, it's the students' job to pick out and eat it nutritiously.. I said I'd answer.. I'm not saying that I'll just tell you what I want...ㅎ.ㅐ.
