I'm a PHP developer as well, and I understand that there are great reasons to do both. One of the main reasons I've been curious to learn rails is because some people say learning rails made them better PHP developers.

Ruby's a great language and a perfectly good choice for a first language.
Rails is a great honking huge web framework with tons of stuff happening automagically in the background. I'm inclined to say that a Rails project wouldn't be a good choice for an early programming project, and that if you want to understand web programming, you'd do better to start elsewhere to get an understanding of the things Rails does for you automagically.

codacorolla, it'd be a mistake to jump right into Rails without learning Ruby -- the language that Rails is written in -- first. Go to tryruby.org first and give that a spin.

Take the initial zombie advice and go to tryruby.org/. At that big window asking for the magic ruby code type "help" and follow the advice they give you. It's really quite easy and before you know it you'll actually know some ruby.
On preview ... damn too slow

This got a chuckle out of me. Been programming web apps since high school, but took a loooong break. Trying to get back into it and sometimes Rails is just baffling, especially when you're used to being involved in every single line that goes into your program...

I learned Rails a month ago to attend a workshop on a RoR-based project after being immersed in the Drupal world with its own particular weirdness. Rails reminded me of what web development was like when I was building sites in ColdFusion - lots of boilerplate taken care of for you, but you are thrown back to the world of processing a request on each page, building the page to respond to the request, etc. etc. and having to build the whole site logic yourself. It was refreshing but I've been spoiled by how much Drupal does for you - not to mention the community.
That said, I'd recommend Rails as a good way to learn the important fundamentals of web development.

People have been saying this kind of thing for years. The problem is there's a kernel of truth to it, but only in certain cases, not as a hard-and-fast rule. When I started building web apps, people tsk-tsk'd when you didn't understand the entire TCP/IP stack. Nerds sometimes need to be reminded the point of programming is not to become one with the machine in a perfect synthesis of human biology and electronic brains, but to get some shit done and then go drink beer.
I am a good programmer because I want to maximize the amount of time I drink beer, not because I am a silicon whisperer.

yerfatma I am on the same page as you are, the reason I think Rails is a good learning environment is because you can get a lot done with it, but you still control the flow of events in a finer way than with a CMS and it gives you more control and I think learn a lot without having to deal with parsing request strings, etc.

Seconding that. I've been working on picking up Rails for the past few weeks so that I can build shit with it. I don't care if I don't know how the entire thing functions 2 or 3 layers down, all I care about is that it works.

The one problem I have had with rails is getting has and belongs to many (or has many through) relationships to work the way I want them to. It always feels like an ugly hack no matter how I do it, and its hard to do anything fun that doesn't at least have a few of those kinds of relationships (as in tags, for example)

Btw, can I drop a random Rails question here?
I have a list of items on a show page, and I want to put them in a 3 column table, and it's easy enough for me to wrap them in the appropriate tags using the cycle command if i want to go left to right, but I want them to fill a column going down, then fill the second column, then fill the third column.
Can anyone think of a way to do that?

You need to at least have a basic understanding of how your underlying DBMS works to be a decent programmer at all. You don't need to know how gratuitous ARPs work or what the ideal table cache size is, but you need to at least know the basics of how a database works. Unless you plan on getting less than 10 records a day.
At my company, we get 10+ million records a day. Which means everything matters. (You wouldn't believe how much the write-cache on the RAID matters. Or the InnoDB buffer pool size.) But even for a small to moderate site, if you don't know the basics like how to properly index your tables for your program's queries, you're going to get bogged down even with just hundreds of entries a day. Active Record is nice, but it's not magic.

My knee-jerk reaction is to agree with you, but I don't know if that's true. As a programmer I (almost) always start with the data design and working with an ORM (I've been working in Django a lot) gives me the hives sometimes (self-link), but I can imagine a few years from now, with improvements in (your favorite) ORM's logic and faster processors/ more memory, that ORM becomes just another layer that people don't have to think about.
Don't get me wrong: looking at the workings of even a nicely-designed ORM is like looking at how sausage is made and I probably drop back to raw SQL twice as much as I need to, but I think you could build useful things without being able to write your own queries. I wouldn't advise it, but I don't think you have to know how to join two tables to build a web app.

The problem is there's a kernel of truth to it, but only in certain cases, not as a hard-and-fast rule. When I started building web apps, people tsk-tsk'd when you didn't understand the entire TCP/IP stack.The problem here is that TCP is, for the most part perfect. It will never fail on you, unless you have bad hardware somewhere. From the perspective of the web developer, you just don't need to worry about it. It will always be there for you.
HTTP itself is ridiculously simple, given the time investment needed, it's really worthwhile to know the difference between request headers, URL parameters and the POST content.
The problem is that once you get into database connections and web server configurations and stuff like that it can go wrong. Once things become rock solid and infallible, you can ignore them. But as long as things can go wrong it's important to understand what it's supposed to be doing.
My knee-jerk reaction is to agree with you, but I don't know if that's true. As a programmer I (almost) always start with the data design and working with an ORMI kind of just think ORM is a bad idea. I've tried to use it and ran into weird issues once the DBs got huge. A much better idea is using NoSQL style databases if you don't need to do actual queries. If you can control exactly how indexes are used, instead of being at the mercy of the DB I think it's much easier to control. I've never done anything in ruby, though.

Heh. Except when you have an mtu mismatch. Or there's a routing problem at your ISP, or your firewall access list is borked up, etc, etc. If you're going to be in web development, you probably don't need to be a cisco engineer, but you do need to know how the underlying protocols work. Because when your client calls in and tells you your webserver is down. Or you need to call your ISP to ask why your webserver isn't working, you're going to need to know what you're talking about.
