PHP-General - Phpinfo completnes

In my php.ini file I have these lines uncommented

extension=php_mysql.dll
extension=php_mysqli.dll
Yet when I run my phpinfo function I do not see them listed.
Is this the norm?

No it's not. Did you restart the web server?

Yes, I rebooted. I made sure there is only one php.ini file. I do have one concern and that is how you set the location for the location of the ini file. The statement that I found was:
PHPIniDir "c:/php"
Is that the only one needed?

The location of the two libraries should be in the ext directory, correct?
Thanks!

phpinfo() will tell you the path to the php.ini file. I would use that, rather than trying to change it.

Yes, I found that line in the phpinfo() output.

I tried this experiment. I repeatedly commented and uncommented the line in the php.ini file that loads the gd_library:
extension=php_gd2.dll.
I then ran the phpinfo() function and the text appeared and disappeared in the output correctly. So now I am more confused.

I was able to resolve this issue by adding the PHP directory to the system path.
