A few months back, I decided that I was going to learn PHP. [...] The reality that I discovered wasn't at all what I expected. Sure, there was plenty of spaghetti code out there (there's also plenty of spaghetti code in C++, Java, take your picků), but there were also a variety of frameworks and communities devoted to using PHP to all kinds of productive ends. I was also surprised at just how much of the internet runs on PHP. I guess that something like a third of the internet up and decided to quietly not mind the haters.
