Great catch, working perfect now with latest HEAD. Any more testers, I

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.
http://gr.php.net/manual/en/ref.mysqli.php
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.

Here is the diff for mysql against DRUPAL CVS HEAD. The change was
proposed by chx on IRC.

versions), as well as releasing them into the public domain. The
changes I made are show in the diffs. An external URL where users can

Using that file, I get this error right away:
Parse error: syntax error, unexpected ',' in C:\Documents and
Settings\tserbinski\My
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,
MYSQLI_CLIENT_FOUND_ROWS);
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).

Forgot to mention tested this with PHP5.0.3 and MySQL 4.1.11 on Windows
2003 SP1.

Thox, the reported duplicate issue is using an out of date
database.mysql.inc file. I believe Drumm added quite a bit of code for
friendlier errors. Seems those two files need to be merged for proper
MySQLi support. I'll see what I can do later today if I have some time.

Ok I've taken the latest HEAD version of database.mysql.inc, merged this
with NSK's recommendations, and then merged that with Thox's
database.mysqli.inc (see link a few comments up) whose database code
was based on out of an out of date version of the include file.
Also went through and tweaked and it looks like this patch is ready to
go. Just tested it here and it is running *now* on average, 40ms
*faster* than the regular mysql library.
Patch needs some more testing but I believe it is ready to go.
Optionally, lines 27 can be removed and the mysqli_real_connect() can
be updated with the $url['port']. No way to confirm if this will work
100% but we can get rid of some extraneous code if someone can confirm.
See attached file.

Thomas this looks like the regular mysql file... nothing changed in
this. Attached wrong file I am thinking?
