PHP Startup: unable to initialize module

i'm trying to install mongoDB in my system. As instructed in

http://www.mongodb.org/display/DOCS/PHP+Language+Center,

I downloaded 开发者_运维知识库php_mongo.dll and put it in ../php5.3.0/ext folder. Then I added extension=php_mongo.dll to php.ini. When I restarted WAMP, I got the following errors:

PHP Startup: unable to load dynamic library php5.3.0/ext/php_gd2.dll

and the same error for

php_mbstring.dll,php_mysql.dll,php_mysqli.dll,php_pdo_mysql.dll,php_pdo_sqlite.dll.

After that, I got another error:

PHP Startup: Mongo: Unable to initialize module 
Module compiled with build ID=API20090626, TS, VC9
PHP compiled with build ID=API20090626, TS, VC6.
These options need to match.

After some reading up from the net, I realize that I have to change the compiler for PHP. Does anyone know on how to update php compiler VC6 to php compiler VC9?

My Apache version 2.2.11 PHP version 5.3.0

thank you

• Download the zip file for VC9 x86 Thread Safe (which is for PHP run as Apache module).
• Extract the contents of the zip somewhere
• Stop apache
• Backup the php.ini file you have in your current PHP directory ../php5.3.0/
• Delete (or backup) the rest of the contents you have in ../php5.3.0/
• Place the extracted content in ../php5.3.0/
• Put php_mongodb.dll in ../php5.3.0/ext/
• Put php.ini back also
• Restart Apache

edit:
Sorry, I forgot to mention that you also need to replace your apache install with the one from apachelounge as well, and have Microsoft 2008 C++ Runtime (x86) or the Microsoft 2008 C++ Runtime (x64) installed, as per the remarks in "Which version do I choose?" on the same page http://windows.php.net/download/

For time being, check which module is in warning message, just go to php.ini file and comment it. This could work
