php_mysql.dll is working fine on my server. Today I decided to start making the migration to using mysqli, but I am unable to get it to load. I uncommented the line
extension=php_mysqli.dll
from my php.ini file and restarted IIS (6), but I still get undefined function. I made sure the php_mysqli.dll file is in c:\php\ext, same as php_mysql.dll.
Any ideas?
