If you want to send SMS via PHP I suggest taking a look at www.twilio.com—they are pretty inexpensive and ridiculously easy to get started with.

What is the best framework to use, Yii or Ruby on Rails?

This is a big decision, and it’s worth taking the time to pick what’s the best fit for you. I recommend going through the tutorials for each one, building the basic application they describe and seeing which made the most sense to you. As a Django developer, I suggest trying that framework too :)

How can I get access to the PHP script of websites like Dropbox?

If a website doesn’t deliberately publish its server-side code (some sites like reddit do this, but it’s pretty rare) then you won’t be able to see it. You can search for an open source clone but these will often be pretty low quality—the smartest open source developers tend to work on libraries that solve common problems rather than putting their efforts in to building complete clones of existing sites.

What are the tradeoffs (e.g. development speed, performance, scalability) between using various php frameworks, ruby/rails, or python/django?  Is there any reason to choose one overwhelmingly over another?

At this point, I’d argue that the decision between them comes down to programming language rather than framework—the frameworks have mostly converged on a very similar set of features.

In what circumstances should one use “magic quotes” in PHP?

Absolutely never. Magic quotes was a badly designed feature, and PHP has been trying to escape its legacy for years. If you are constructing SQL strings using string concatenation you’re asking for trouble—use prepared statements or a library that interpolates and correctly escapes variables for you.
