All the web servers and hosts gives that they support Php. non of them says that they support ASP Why is it so? or does every server by default provides ASP?

PHP and ASP require different operating systems to operate on. PHP needs Linux while ASP needs Windows. You cannot run two operating system simultaneously, so that's why some support PHP and others support ASP and none support both.

Most windows based servers will support ASP by default. It is possible to offer hosting with php and asp together (http://www.stpwebhosting.com/ --> reseller hosting account) because php can be installed on windows and asp can be installed on linux (at least chiliASP used to do this).

I imagine that PHP tends to be offered by free hosts more often than ASP because it's cheaper to deploy.

PHP is made for Linux Servers.
ASP is made for Windows Servers.

PHP is good and open source.. Its says, I will give my services to everyone. I will provide libraries to be integrated to any type of server and any OS.

ASP is not as good as PHP. It says, I will rather stick more to Windows so that My company makes more profits selling Windows Server and OS. So that people suffer and cry if they are on linux and want to use me.

Now, Running ASP on Linux servers using forced mods is kinda risky and can open serious security holes.

PHP on other hand provides support to be easily installed on Windows Server.

So, people with Windows as well as Linux servers have PHP but people with Linux Servers cannot have ASP. IF they do, they might be risking the server and also degrading the server performance.

Hence, you find PHP everywhere, but not ASP.

I hope this helps.

Just as a personal opinion...

PHP owns ASP.

More scripts, free stuff, etc.

Nice analogy OpaQue

Actually PHP can be used on Windows too. ASP however is only meant for Windows since Microsoft developed it.

PHP is free and open-source and alot better than ASP in terms of stability, features, wide population of programmers, requires low resource.

ASP is paidware, closed-source, developed by Microsoft, more security loopholes and vulnerabilities, and usually used by big companies because of the reputation of Microsoft.

Basically PHP and ASP operates the same function.

I used ASP at one point. It provides little debugging tools that I know of, ih any. It is tied to two languages, both not object-oriented. It is a pain to work with. PHP is open source. It has several good debugging tools (like Dev-PHP) and a large user community. Along with free software comes free software. This means that you can get everything needed to run PHP (aside from hardware) and many things that run under PHP for free. Personally, I perfer ASP.Net, but I think that ASP is old, outdated, unreliable and just stinks. (Note: Much of this is personal opinion, not fact.)

That's not quite true. You can run both PHP & ASP on a Windows box.
