What is the difference between PHP, ASP.net and Java script?

If you would like to build a dynamic website, I recommend PHP all the way. Don't use ASP.Net, its slower and there's more of a community for PHP. PHP can also run completely free. That is, ASP can't run on Linux (free) PHP can.

PHP and ASP are server side languages. The processing is done at the host computer.
Javascript is a client side language. It's not a full language, so relies on something else like HTML to develop the page.
JAVA is a full language that works for developing applications or websites.

Which to choose depends on what you want it to do and what you want to spend.

If you are storing a lot of customer data, then you'd want to be server side.
A lot of flashy presentation but not much change in content would be better suited for client side.

You don't /need/ to know any of them to build a website.

ASP and ASP.NET are server side environments in which you can run programs, typically written in C# (ASP.NET) or VBScript (ASP).

PHP, Java, and JavaScript are all programming languages. They can all run on the server.

Java and JavaScript can also run in the browser (although support for Java Applets is generally weak these days).

ColdFusion is a tag library for Java. It adds some shortcuts when writing server side Java.

And there is JSP. It's like PHP and ASP. Its architecture is great, but for most website, PHP is much more practical.

these days most of the sites use php

Right, php, coldfusion and asp.net are server-side scripts while javascript are mainly client-side script. You could identify them by their extension name: php, cfm, aspx and js.

Thanks for these nice posting,these are very useful..................
