I've been playing round with the Google App Engine Runtime for PHP. In addition to this, I've been using Slim Framework for a lot of projects, both in work, and at home.
I figured I'd give deployment of a Slim Framework to Google App Engine a pop. Unfortunately, I hit a snag.
It seems that Slim checks for a key in the SERVER array called SERVER_PORT.
When you try to load it, you get this error message logged:

Fortunately, fixing this is kinda easy (yet a bit hackish).
Stick this at the top of your index file:
PHP Code:
<?php
$_SERVER['SERVER_PORT'] = 80;
Granted, this isn't a long term fix, and when I figure out the ins and outs I'll report back, but for me, right not, this works.
