Php has says to make things really insecure and unlike your book on Ruby which probably shows you the right way to do things there, w3schools doesn't tend to. It's not a huge deal while learning if you're a quick learner and don't get bad habits but it's worth being aware of and looking into if anything gets serious.
If you want a really over the top look at why some people don't recommend w3schools, check out w3fools.com
If you're looking for a solid php resource with a more modern and secure approach I'd recommend http://www.phptherightway.com
Overall it's probably just worth noting that wherever w3schools recommends something you wouldn't do in Ruby it's not because you should do that in PHP - and it'd be worth looking in your php book or other resources for the right approach in PHP.
I have been spending a lot of time lately studying outside of school, but it can be difficult to know what to read, what to code, what to learn. So I appreciate the feedback from knowledgeable people very much.
I have seen that the pragmatic programmers write very good books that have great reviews so I will stick with them for sure. I will look a bit more critically at w3schools, though, and I will definitely check out the php site you recommended.
I would love to hear more advice from people in the industry on what I should be learning and how I should be learning. If you have any ideas about how I should work on more practical things outside of school to give me real world skills I would be grateful for an email: [email protected]
I don't work on these all at the same time, but since I am out of school for 4 months in the summer I have had a lot of time to spend a couple weeks working on one project, and then a couple working on another, and so on. I don't have a schedule for myself, but I try to do some programming every day. There are a lot of technologies I would like to learn; I have a whole career in the future to specialize and learn something VERY in depth.
Also, I'm a quick learner ;)
EDIT: Forgot to add Git to the list in the first post. Something else I started using this summer.
