PHP and MySql
Finally, my simple insert call to MySQL using PHP worked.
Working with open-source software could be too much of a headache. These are some of the things I did to make this work. Posting this here to remind me and maybe help out anyone who might encounter the same problems.
1) Placed c:\php in the Path environment variable.
2) Uncomment also the extension php_mysql.dll in php.ini (not only php_mysqli.dll)
3) Restarted the PC (some weird error came out when loading the dll)
Also, I downloaded and installed phpBB 2.0.20. It has a very critical bug. An error occurs when Accept is clicked during Registration. Maybe this is a degrade from the previous version since this is just a new bug dated Wed May 10, 2006 12:14 pm. Here’s the link:

Open-source softwares need a lot of improvement in both documentation and quality assurance. Maybe some open-source developers are just too lazy/busy to document and test their work. Or maybe that’s is just how open-source works. They code and we, the end users, test. 
Aside from those problems, they work great.
