As has been pointed out by others, you are constantly accusing the
authors of web sites and books, of not doing their jobs correctly,
when the problem is that you simply do not possess the intelligence to
understand what they have written.
You have purchased an excellent book on php and yet you say that it if
full of stuff that you have to be a super technician to understand.
BULLSHIT. Lots of people by that book and if they were super
technicians, they would not need to.
Stop wasting your time and money. Take up a hobby that does not
require you to use your brain.
