I installed XAMPP 1.7.4 with the installer. It seem to work fine. I want to also install Drupal 7.0, but it requires Apache to have both php_pdo.dll and php_pdo_mysql.dll in the php/ext directory. I am missing php_pdo.dll in my php/ext directory. I followed the instructions on http://drupal.org/node/549702. Even though I found the ini file and added the lines to add the dll extension and restart the web server, the actual php_pdo file is still missing in the php/ext directory.
I'm not sure why it's missing the file. How do I get the file? Thanks.
