How was MyLifeisAverage made in PHP?

[...Hey.]

I am making a website quite like Mylifeisaverage.com, but it has a different theme. I was able to make a layout and everything using xhtml and css, and I know a bit of PHP. I was wondering how the system was made. I know how it works; posts are sent to a voting page, and once they reach a certain amount of votes, they are sent to the main page. I understand that, I just have no idea how it was coded. I made a database in MySQL, but I don't know how to use it like this. I made the forms for submissions and everything, but I just need to know how to do this. Thanks.

I am learning PHP too! I am not sure exactly how, but there is some info on how to call MySQL, and stuff like that: http://www.w3schools.com/php/php_mysql_intro.asp

I think this is what you need more though, how to Insert: http://www.w3schools.com/php/php_mysql_insert.asp
