After looking at your phpinfo()
output, it appears the mysql extensions are not being loaded. I suspect you might be editing the wrong php.ini file (there might be multiple copies). Make sure you are editing the php file at C:phpphp.ini (also check to make sure there is no second copy in C:Windows).
Also, you should check your Apache logs for errors (should be in the logs directory in your Apache install.
If you haven't read the below, I would take a look at the comments section, because it seems like a lot of people experience quirks with setting this up. A few commenters offer solutions they used to get it working.

Another common solution seems to be to copy libmysql.dll and php_mysql.dll from c:PHP to C:WindowsSystem32.
