What are common pitfalls when setting up an osCommerce-Shop with PHP, especially regarding the include_path configuration?

When setting up an osCommerce-Shop with PHP, a common pitfall is incorrectly configuring the include_path directive in the php.ini file. This can lead to issues with including necessary files and libraries within the application. To solve this, ensure that the include_path is set correctly to point to the directory where the osCommerce files are located.

// Set the include_path in your php.ini file
include_path = ".:/path/to/osCommerce/includes"
