You need to do what I did, which is what you're doing right now: Find the people online who are doing PHP and Rails, and hang out with them there. Use IRC. Join an open source project. Since you were crazy enough to mention PHP in your list of higher aspirations, let me point out that the Drupal project could really use good coders, to say nothing of good documenters. ;)
You'll always find better hackers by traveling to them online then by traveling to them in real life. The work is all on the screen. I learned web development because I started reading Greenspun's website and just kept going. Now you've got PG's essays and this site, which would have been like heaven if they'd been around when I was an undergrad. Now that the podcast, the screencast, Youtube, git, Sourceforge, and Trac have been invented you can have a flourishing career without ever meeting a teacher, a collaborator, or a customer in person. They could all be in completely different countries.
Of course, you might still want to meet your collaborators in person if you want to do a startup. You could switch universities. :) You could plan to get your first job in a startup hub where you can seek out news.yc readers. You could take some trains to NYC and attend the Rails user group there. They were still a happening thing, last I heard. Zed Shaw might turn up, and that guy is a trip.
Meanwhile, I have a physics degree, so before I say any more my guild requires me to issue this advice: "To heck with C and Java, and with PHP and Ruby for that matter; you're in college, so spend your spare time taking all those physics courses (or econ, or linguistics, or molecular biology, or art...) that you can't get anywhere else! The web isn't going anywhere, and it's better at teaching you web technologies than any school."
UPDATE: I left out statistics. You want to learn a really valuable, somewhat tedious black art that most people don't understand, to their peril? Take an intro statistics course.
