btw I wanted to try Joomla and when i uploaded files and tried to install joomla it showed me a message that host needs to support php 5.2.1. But my host supports 5.2.1 dunno why it don't work

Means you don't have the UP to Date version of PHP, Make sure your host has the latest version of PHP installed otherwise you'll keep getting this error. Always check out the specs of the software before installing it so that you may not get disappointed at the end
