Over on the InformIT website today, there's an article for those out there that need a way to work with more than one database at a time in their scripts. Multiple Database Interaction in PHP 4.1 covers some of the basics of three different ways.

These ways (PEAR:DB, a custom DB wrapper class, and the DBX layer) are all just a bit different in their use, but examples of each are provided. These examples assume that you know a bit alredy about how to work with databases, and how to fetch/enter information into them. It's not a "using databases with PHP" primer or anything...

The examples given are excellent - I wish all articles would do it more like this, with a line-by-line breakdown of what each thing is doing - very nice.

Thanks to Ewald for the pointer to this article...
