How to update php version in xampp?

[apaj]

I have xampp-win32-1.7.1 installed in my windows xp professional
But I have a website hosting provider using PHP 5.2.11 and phpMyAdmin - 2.8.2.4 and MySQL 5.0.5

How can I update PHP from 5.2.9 to 5.2.11 in xampp installed in my computer?

I'd like to have the same php and mysql version in xampp to my computer as my Web Hosting Provider.
