Please Help...
 

I am so confused on how to get my vbulletin forum. I was looking at the manual and i really need help. it said

"Note:
Before installing vBulletin you need to have PHP and MySQL and have created a database within the MySQL engine to hold vBulletin's data."

How do i get a php and mysql database server thing, i thought i could just buy vbulletin, download it, and use it i mean can someone please tell me what to do before i get it...
