Hello everyone:

I have come to love the ease of updating PHP, since getting used to
using it these past few years. Recently, however, when I upgraded from
PHP 5.1 to PHP 5.2.0 and again when moving to 5.2.1, I noticed strange
behavior when trying to load php_mysqli.dll. I am using Apache 2.2.3
on Windows XP Pro (32-bit). I use the php5apache2_2.dll to load PHP as
an Apache module. The PHPIniDir directive in httpd.conf points to the
correct directory. I also have the older php_mysql.dll extension
loaded simultaneously, which works fine. However, in phpinfo(), MySQLi
is nowhere to be found, and trying to use any mysqli functions or its
class will yield an error saying that they're undefined. In php.ini,
the extension_dir directive points to "C:\php5\ext\".

As for the environment, I have my PHP install dir in the _System_ PATH
(it's been there for a long time): C:\php5. When I install, I just
move new release into the php5 directory, so necessary DLLs for
extensions do not need to be moved, and older versions can be
overwritten for newer releases. In fact, mb_string, mcrypt, GD2, cURL,
php_mysql, and many other extensions load just fine. However, the only
way I can get MySQLi to load correctly is by moving libmysql.dll into
my C:\WINDOWS\system or C:\WINDOWS\system32 folders.

I simply can't understand why the problem lies only with MySQLi. Also,
when I restart Apache, there are no errors. The MySQLi extension
directive in php.ini is also uncommented, by the way. :-)

This has only started to happen since my past couple upgrades, so I'm
not sure exactly what to make of that.

Thanks for any time you have spared and/or can spare on me,
Curtis
