Recently I came across some code snippets and it's full of mess, lacking fundamentals, lacking basic code separation... That made me to wonder why some developers aren't learning the basics before trying anything.
Since I have been asked to interview experienced PHP programmers, I was preparing few interview questions. I came to know, most of the people ask questions found in the Internet; most of them are like "What is the function used to connect MySQL DB in PHP".
