For you IIS people that are wondering why the instructions still don’t work even with a perfectly configured PHP.INI file. This may help: You MUST copy the “libmysql.dll” file from you “\PHP” folder to the “Windows\System32” for it to work. Even if you have commented out the appropriate lines, and done everything else perfectly, and that file is missing from your system32 folder, you’ll get that message. Reboot your machine after you’ve copied the file.
