Umm... no. I was talking about the subset of devs which are just chugging along without much thought put into the craft of programming. Which includes me sometimes, as well as many PHP developers. But not all of them.

Go search internet forums: "how i script PHP mail?" folks won't use the latest best practices.

And there were dynamic webpages before PHP, PHP just gave a ton more people access to them by easy installation, configuration and most importantly, development/feedback cycle.
