1. PHP’s Evolution On The IBM i Platform Continues

   PHP was one of the first open source languages and runtimes to come to IBM i way back in the early 2000s. More than two decades later, open source is thriving on IBM i with hundreds of projects, while PHP is considered a hardened, enterprise-grade language for modern Web applications. This fall will see at least one new release of PHP coming to IBM i, version 8.6, and perhaps more.

   Here’s the scene: Janet is perusing the computer aisles at Costco when suddenly she sees it: The exact configuration of a MacBook Pro she’s been looking for, at a really good price. As she’s getting ready to buy it, Janet makes a grim discovery: Costco is out of that particular MacBook Pro, and the item on display is the last one in the store.
