PHP or ASP

I am not really sure what any of these are. Sorry I could not help you.

i think php is better as is platform independent and do not require you to invest money i.e php is fully free and open source created by web developer for web developer so rather than using ASP i think using PHP is better

It's not that simple surely? PHP is more popular than ASP.NET because it's free and it runs on Apache, but you can't just say that one is better than the other, it depends what you're trying to develop and who for. Ok, so PHP is open source. You can argue that that makes it better although I don't think the arguements are cut and dried. And ASP.NET controls are embedded into HTML as well, although, like PHP, the processing is done server-side. PHP has built in features? What features? And why would they be any different or better than the features built into, say, C#.NET which has a huge class library and is fully object-oriented? The fact that PHP is often used with MySQL is neither here nor there. Both platforms support a variety of dbms. But I agree it does win out on the compatability front. Of course if you're working in an environment which uses Windows server to provide a Web server then that isn't an issue. And there are still plenty of those about, particularly at corporate level. I've used, and continue to use, both platforms and it's horses for courses. Except that JSP is better than both :)

on my exprience PHP is the Best, Because it is availble free and have free documentation and do not have anothe support softwares for run PHP and Apache is the best web server and tomcat is the advanced server
