This was code written in PHP 3 and part of pricing and tax calculations on an import with data coming in from a custom made inventory management system module for an ERP solution running on Windows outputting the most god awful XML in UCS-2 with node names that contained accented characters, and converted that data into temporary MySQL tables for the custom made web shop.
Fun fact: the import, to take into account the fact that product IDs could change (as the entire product database with over 50k products was rebuilt with every import), would also update the IDs of all items in customers' shopping carts at the time of the import. Great fun if the customers had a product in their cart that was discontinued or changed.

That single function was 56 kilobytes of code.
