Sorry guys -- I'm not going to argue the differences of Java, PHP and .NET.
Java is very solid, and PHP is a tight scripting language.
I do use PHP on a regular basis, and we have some very hardcore Java programmers over at SitePass.
If you just want to simply display/edit/delete simple data, I would use PHP.
If I wanted to build a solid Web Application, I personally would use ASP.NET.
