The source code is here: class.qbrds.inc Thanks to many of the folks on the Inutit deveoper's web site for making this possible.

Based on a few comments, we've added a bit more wrapper around it so "out-of-the-box" you can pull the whole chart of accounts out of QB RDS Server. Those modifications are here: rdsclient.php Using this version, you know something is working, when it works.

This code instantiates a PHP/Linux client that finds and exchanges messages with the Quickbooks RDS server. It helps if the PC running your Quickbooks RDS Server is behind a firewall that allows the specific traffic through. In addition, it is required that the PC host name be listed either as a FQDN DNS entry and/or listed in the client's (i.e. web server's /etc/hosts file. SSL traffic requires the DNS entry to match the host name of the target machine.

You have to build your own QBXML messages to hand off to this object, which returns a response QBXML message from the RDS Server it targets. This has been tested across the Internet from a public web server to private PCs.
