[support] Best way to post content from PHP

I'm looking to setup a script to automatically create a monthly report page in drupal from my custom database. I was hoping to use the BlogAPI module to post my data from my application to drupal, but have had little luck in finding a PHP script that can do this for me that still works (most are outdated trying to redeclare XML-RPC functions built-in to php).

Anyone have any experience doing this and could shed some light on the subject? Am I just going to have to write my own XML-RPC calls or is there a pre-built library that can do this via one of the supported APIs (blogger/mt/etc)?

TIA
