What is the main difference between these two language php and asp? Also explain which is more useful?
I think According to me php. It is user friendly, robust, modular, powerful and very much secure software.
I think asp is easy to learn but php has lots of feature then asp the new version of php also support oop programming
As for ASP handling a more complicated app than PHP I'm not sure that's true. One thing I like about PHP is that you can extend it with C extensions, even dynamically loadable. I've also been able to run a very stripped down version of PHP on a VPS and also open source code by compiling a minimalist version and running on low memory.
i think if you learn either one you'll have a good grasp about the rest. but personally i'd go with php
