No, the web exploded in popularity as a development target because the labor pool is so diluted that it's easy, quick, and cheap to hire (and fire) any random "webdev" who is good enough for their purposes. And that's why, unless I get desperate, I wouldn't put PHP on my resume and would only list non-webapp projects for other languages I've used professionally but which are also used for webapps (e.g. python)--I don't want to put myself into that (cheap) labor market.
