Can someone help me choose a web programming language?
Use PHP for programming — it embeds straight into HTML pages, you can do anything with it and it’s Open Source, so it can be found on any server (not proprietary to a particular operating system). And use MySQL for the database. It’s also Open Source. Speed of information retrieval is dependent not just on what language you use, but on how well you write your application and organise your database. If you don’t create indices on the right fields, queries are going to be slow.
