installing PHP5 and mysql 4.1

I've tried everything the faqs say and I'm still unable to get mysql support in PHP5.. I've added H:\php to my Windows PATH variable (H: is my main drive) I've uncommented php_mysql.dll I've added the extension directory to php.ini Rebooted the server Before doing the above, phpinfo's output had absolutely no instances of the phrase mysql in it, showing it neither disable or enabled. After doing the above, phpinfo does show the mysql directory added to some environment paths, but still no table showing whether it's enabled or disabled. Am I missing something? One faq says not to use mysql.dll but mysqli.dll ?? where is this? Can anyone shed some light on this subject for me? When I run a mysql test script php returns an error in the line with mysql_connect saying it doesn't understand the function. (which tells me mysql support isn't working)
