I added MySQLi support to Drupal by adding a database.mysqli.inc file.
After chx's suggestion I also removed $row from db_result from both
mysqli and mysql files.

Users are supposed to connect to Drupal with a mysqli "URL" in their
settings.php. Just adding an "i" in the mysql entry in settings.php
would work.

MySQLi is the new MySQL client in PHP which connects to MySQL 4.1, 5.0
and beyond. MySQLi replaces the older MySQL library which was popular
with MySQL 3.23 and 4.0.


The older MySQL client does not support full functionality with MySQL
4.1, that's why MySQLi is important.

MySQLi works in PHP 4.1.3 or above, and is more popular in PHP 5.

MySQLi means MySQL Improved.

This patch should be included in core.

Using that file, I get this error right away:

Parse error: syntax error, unexpected ',' in C:\Documents and
Documents\websites\drupal_cvs\drupal\includes\database.mysqli.inc on
line 34

Doing some digging through the documentation, it looks like the
mysqli_real_connect() [2] is being used *improplerly*.

This function call works with no problems:
  @mysqli_real_connect($connection, $url['host'], $url['user'],
$url['pass'], (substr($url['path'], 1)), $url['port'], null,

If this is indeed the correct call (it appears to be but can't really
test whether the ports, sockets part is working), then the code circa
line 27 that checks for the port can be deleted since the function call
handles this.

Additionally, the database check on line 51 needs to be moved up since
the database is selected during the mysqli_real_connect() now.

Overall, code needs some work and cleanup.

Peformance wise, noticed a 10ms decrease in page generation times for a
few pages (not thorougly tested performance wise however, just a quick
and dirty observation).
