It really depends what you are most passionate about.
One of the the simplest thing that you could do is start a content blog of some sort but you'll have to write articles daily and come up with new ideas for new articles all the time. Only if your articles are interesting, useful, and consistently updated will you have a money making blog on your hands.
A forum takes up a lot of time and computer resources. It's a huge thing to manage successfully and contexual ads usually don't work. However, if you have a friendly community then you could probably sell forum related stuff to them. In my opinion, a forum is one of the hardest things to manage/monetize because of all the people management. Another problem is that it takes up a whole lot of server resources and you'll have to upgrade your hosting fast. I've had a big board since 2002 and it still gives me problems hehe.
Other choices you might have would be to probably affiliate programs. Sell stuff for people on your websites. Again this is difficult and you'll probably have to advertise your site everywhere.
You say that you have experience with php and mysql then I think you could create some sort of application site that will be so cool that it will become popular using word of mouth. You could put ads on it and stuff.
Basically, anything that you make needs to get HIGH traffic and you'll pretty much be set  .
As for hosting... please check out my sig (the yinyang smiley). I host with ASmallOrange and I can HONESTLY say that they are one of the best hosts that I've hosted with  . If you follow that link I'll get one month free hosting. You can check them out and you'll find reviews consistent with what I have to say (that they rock!  .. if you do choose them please write garg in the reffered by field (i'm so shameless :O )) .
Good Luck! I have the same sort of goal as you. I'm seeing some results but I feel like I reaaaally have to push harder
