Comparison

PHP vs Django/RoR

Yes Django wins.

Yep you guessed RoR wins.

Wrong comparisons ...

STOP

Pro's & Con's

Con #1: Legacy code

i.e. Mantis Bug Tracker

first commit

Fighting some old & dirty legacy code in RL :(

Con #2: Easy to start

Let's you shoot yourself in the foot

Beginners hacking away

Con #3: Language inconsistency

underscores: isset vs is_null

abbreviations: call_user_func vs create_function

parameter orders: in_array($needle, $haystack) vs strpos($haystack, $needle)

Pro #1: RTFM

Great resource manual for almost every function/method on php.net

Years of community effort filled with examples and suggestions

Pro #2: Easy to start

Yep it is pro too

You can see results of your work in minutes

Cheap & widely available hosting

Pro #3: Evolving constantly

Maybe "New kids on the block"?

How ever we will call them..

clean and modular, OO and MVC frameworks

coding format standardization

slows down reinventing the wheel

improves code re-usability

supports git repos directly
