As those responding to support requests in these forums are all volunteers then you will always have to wait until one of those who respond have the time to do so - the quickest way if you are in a hurry is to search the forums first before posting a request for help.
Click on this link as I found many results using these keywords Cannot load mysql extension
in forum XAMPP For Windows.
This is one such resulting post that may help:http://community.apachefriends.org/f/viewtopic.php?p=131399#p131399
When you have phpinfo()
open in your browser look for line:Loaded Configuration File
In XAMPP it should be C:\xampp\apache\bin\php.ini
<--your path to xampp may be different.
You may have a php.ini file in the C:\Windows folder in which case you need to rename it or delete it as it will be in conflict with the one that XAMPP uses.
