yellow1912:
A ruby script written by a noob can never compare with a php script written by a pro.
And if you like Rails, look into CakePHP which is very similar to Rails.
Thank you, this is pretty much what I wanted to know about.
afo:
The more widely used a language is the more likely it will continue to be used even if something "better" comes along.
O.K. I thought it might be so, but wasn't sure if these newer languages (or framework really in this case) could topple the giants, or if the giants tend to go the distance over time. I guess I should have known just by thinking about titans like C that have been around forever and continue to be useful.
kobra:
I agree with afo - learn both to insure you are valuable
I will look into learning a little ruby, but in the end may let go of doing two languages, and try to get good at one.
wilt:
Zen-cart is written in PHP and that won't change.
This is part of what I was secretly wondering "Will there be a write of Zen-Cart for Ruby". Now I know the answer to be "no, php is the language of choice, and the programmers can do excellent things with that language because of their skill level"
Thank you all, I feel like I can settle down a little more for the time being.
