On Reddit.com there's a post sharing some opinions on where to look for PHP jobs and find "the good ones" out of the sea of positions.

I don't want to make this a "hire me" post, because that would and should get downvoted, but where would a person go to find interesting PHP related job ads in 2013? Some of the older big job sites like Monster and Dice are a barren wasteland of boring recruiters hiring for defense contractors, health insurance companies and low end agencies. Github has a small but decent section. Stack Overflow has some decent ones. Hacker news has a monthly thread, but a strong anti-PHP hipster bias. Reddit, at least from search has so few that I find 2 year old ones.

The responses range from links to specific companies looking for people out to some more general resources like LinkedIn, Craigslist, and yes, even recruiters (just be sure to pick a good one).
