No need to be aggressive. It's the willingness to learn that should be important.
Exactly my point. You misunderstood me, I am not aggressive it was just a test of LOGIC. Programming logic. I've already told you what you should master.
Thou most programmers, hackers, developers all learned from someone, whether it was a book, video, etc
As PHP (the most used for web developing) is a well documented language and you can find examples and different script developing tutorials all over the internet nulling is not something that you can find on the internet.
Why?
To get an answer to this "Why?" you have to know what actually nulling mean and why nulling can't be learned as you learn to program a script. As creating a simple page that will display some query results is more or less exact and can be learned from a tutorial nulling is only about LOGIC. What does this script do? Where it return its values? Why is another snippet that returns a different value?
Why nulling is not an "exact science" and cannot be learned from tutorials? Because there are different ways to reach the same result. As some developers use pre-built licensing systems like Freemius others are using proprietary developed scripts. You have to find the LOGIC behind these scripts and use it to get your desired result.
If you were a programmer/developer you would have known that. And yet when I am pointing you (as in everyone asking) to the right direction it's always that I am jumping at throats. Where's the logic in that?
