So are you implying that you're not filled with the spirit of the proletariat when you program in PHP?

That was my initial reaction too, but then I found it hard to disagree with (in the general case of course) and instead thought maybe it's an astute and interesting observation.

The more familiar slight is that it's 'the language of choice for script kiddies', but I suppose they've grown up and gotten apprenticeships.

I think the implication is that PHP is a language that has been accessible to those who didn't join the programming profession via the traditional academic route (CS, CE, EE, or Math degree from a University).

And that's pretty well borne out by its history, and is part of PHP's enduring appeal to many people who don't have formal educational backgrounds in the computing sciences.
