Differences and Similarities between PHP and Ruby on Rails

A very interesting post since I have been keeping an eye on RoR for sometime now.
Some snippets below…

There are rather significant syntactical differences between PHP and Ruby. For example PHP requires semicolons at the end of lines and generally requires curly brackets to enclose blocks of code. Ruby, on the other hand, uses newline characters to denote the end of a line of code and many code constructs such as function definitions, and various loops are ended with the word “end” rather than being surrounded by curly braces.

And their similarities?

Before getting started, I know that PHP and Ruby have very significant syntactic differences and different people may prefer one over the other. So it may be harder to implement certain features in one language over the other. Nevertheless both languages can do almost the same things. Both languages have try/catch/throw style exception handling. Exceptions are new to PHP5 as PHP4 does not have them. Both languages can be used in an object oriented way. Ruby has more powerful object oriented features but most developers probably won’t notice a difference in a normal web application. Both languages have additional functionality that can be added through libraries. In general, when developing web applications, I have not yet run into a time when I was working with one language and hit a road block where the language I was using was not capable of expressing the functionality I needed. Sometimes things are easier in one language versus the other but both PHP and Ruby have been able to “do” the same things.

And then the author’s conclusion…

I suspect very few people will argue that PHP is a more elegant language or is more powerful than Ruby. Frankly, Ruby is probably may favorite language that I have ever worked with and I have worked with Classic ASP, ASP.NET, VB.NET, C#, Java, and Perl all rather extensively over the years. Ruby is both highly expressive and concise which is rare and refreshing.

Rails is a very comprehensive and effective web development Framework and there’s nothing exactly like it in PHP. You get a huge amount of functionality for free. Developing in Ruby on Rails is also a very fast process because Ruby is a very concise language requiring much less typing than any other language I’ve worked with. CodeIgniter is a really nice PHP framework. It will give you a great boost when developing your next PHP application.

The hosting and deployment struggles with Ruby on Rails is a major sticking point for me though. As the owner of a web development company many of our smaller clients do not have the budget for their own VPS account and even if they did, we don’t have the staff to manage a large number of VPS accounts or dedicated servers. Keeping the security updates current, managing any issues that may occur with email, and all the other headaches that go along with managing your own VPS or Dedicated server is more than we care to take on for the relatively small, practical dfference between PHP and Ruby. For large projects, it may be worth the trouble, but for small to medium sized projects, PHP is much easier to deploy, less expensive to host, and the language is capable of taking on everything those types of sites require. For our projects, development time with PHP is not noticeably longer than with Ruby on Rails. Ruby on Rails integrates a lot of things for the developer.

There is ActiveRecord for managing the link between models and the database, migrations for keeping development and live databases in sync, built in testing, the ajax – prototype javascript library is included, and you get a well defined file system structure. While it may not all be packaged together as well, PHP can do all of the above.
