关于php.net的后续说明仍然无法使mysqli扩展工作

I uncommented this line in the php.ini file: extension=php_mysqli.dll and my extension is "extension_dir = "ext"".

The php_mysqli.dll does exist in the ext folder.

I am using php 5.5+ so I should not have to manually set the path for libmysql.dll.

Running mysqli_connect yields a fatal error.

I do not understand why this does not work. When I did this with my php_sqlsrv_55_ts.dll file, I was able to connect to sql server immediately. I do not see anything I missed in these installation instructions:

http://www.php.net//manual/en/mysqli.installation.php

Where do I go from here?
