Creating a Page WITH PHP code

Hello,
I’m trying to create a page on my wordpress page with PHP code in it.. but but but the php code just pops up as code, and wordpress only handles the html code.

How do you add Pages with PHP in them? the code I’m trying to have on my site is:

<?php
require(‘./bf2s-mlb.php’);
$mlb->debug = true;
$mlb->get(‘43937143,38233720,45056512,12700542,47991489,45131539,47991439,45131539,49282662,47991563,47694687,44603743,47898166’);
?>

<?php $mlb->showList(‘SPM’); ?>
