The languages of the World

Languages are either "tag" based, like HTML, Cold fusion, or "script" based, like Java, ASP, PHP(open SOurce), JSP

JSP is designed to work with very large, high volume sites that connect to enterprise databases. It has a set of tools called JavaBeans and Enterprise JavaBeans (EJBs) that are designed to move all the scripting into libraries. These libraries are linked to the page rather than placing the script on the page. Libraries allow you to easily change the logic of the application without having to change every page

PHP is a hybrid of tag- and script-based languages. It is widely supported, because it is a public domain language. You don't need to buy a server to implement PHP PHP is one of the fastest growing languages on the web
