Drupal 6.13 Installation - Database Error

Question

I'm using Wampserver 2.0i with php 5.3.0 to install Drupal 6.13. During the installation I'm receiving the message below during the "Set up database" phase

Operations on Unicode strings are emulated on a best-effort basis. Install the PHP mbstring extension for improved Unicode support. (Currently using Unicode library Standard PHP)

Your web server does not appear to support any common database types. Check with your hosting provider to see if they offer any databases that Drupal supports.

How can I solve this problem ?

Answer 1

It's not detecting MySql or PostGres, you either need to verify an installation of one of those, or write your own database wrapper.

Drupal's Database Abstraction Layer

Answer 2

Drupal is currently borked on PHP 5.3: that may be the source of the issues you're running into as well.
