If the question was, "which language is not to learn?" than I would know the answer: "PHP".
And why?
If I answer that I would probably offend a lot of people. So, I'll pass on it this time.
Also, last time I checked axioms do not require proof.
You started the troll...
My posts are reflection of my personal experience... which is rather relevant and extensive... if you do not like it feel free to ignore.
There is no bad language only bad programmers. PHP has the best documentation ever, the most servers running it and since version 5 allows object oriented programming... Sure it offers so much freedom that if you do not code clean your program will be a mess...
True, but somehow bad programmers tend to gravitate to PHP. It is like a bad neighbourhood which is best to avoid...
Friends do not let friends to do PHP, you know.
