I have checked all those MySQL and PHP operation as well as Mediawiki placement, and have attempted "click here" below the sunflower, I’m faced with the following bug despite a lot of checking with uncommenting "extension=php_mysql.dll" at php.ini
PHP 5.2.0 installed Could not find a suitable database driver!
For MySQL, compile PHP using –with-mysql, or install the mysql.so module
For PostgreSQL, compile PHP using –with-pgsql, or install the pgsql.so module
After much trial and error, I changed the extension_dir parameter in "php.ini" to point to "c:\php\ext" from just "./" and finally mediawiki installation form turned up at …wiki/index.php
