This package also comes with another sub-class named mysqli_oauth_client_class that is specialized in executing the SQL queries to a MySQL database using the mysqli extension. If you use a different type of database, you can use this sub-class as model to execute SQL queries using the appropriate PHP extension.

“No input file specified”

Magento/Drupal/Joomla
Many PHP applications experience this error(mostly on Godaddy). There are several solutions that can resolve this. You can try these steps to solve this: ‰‰ 1.Make sure that your hosting service uses PHP version 5. In your root directory, there might be a file called php.ini. If so, rename it to php5.ini. If you see files with names such as .alias, .bash_profile, .cshrc, .screenrc, you are looking at the root directory. If you're unsure, ask your hosting service. ‰‰ If that doesn't work, add the line cgi.fix_pathinfo = 1 to the end of php5.ini. ‰‰ If that still doesn't work, add the line Options –MultiViews to the top of the file named .htaccess. ‰‰ If that doesn't work, search the knowledge base and forums at http://magentocommerce.com for help.
