It really depends on what types of place you're working at. In the past 6 years or so, I've worked on a lot of PHP, and nearly all of it was pretty high-quality, because I don't like working at companies that don't care about code. My point is, if you have the luxury of the same filter in your job choices, PHP isn't necessarily the big red flag it could be. The only exceptions for me have been when I've had to deal with someone else's codebase, or with Wordpress (and Django once), but again, I wouldn't personally take a job where those were the main responsibilities.
