This is the most important question that comes in the mind of every new Wordpress developers NYC. New WordPress developers often find it difficult to understand. As for reasons, most of them see or use it merely as a CMS (Content Management System). Honestly, this is just a one reason why this doubt is always doing rounds in the mind of new WordPress developers not only New York but also in many other parts of the world.
There is one more reason of it. This reason is certainly bigger than the first one given in the first paragraph. Most of the experienced WordPress and PHP developers New York see their juniors asking this question to them because they are not completely taught about PHP. According to them, a lot of people focus on learning just WordPress straightaway. They spend very little time on learning PHP thoroughly.
