(PHP) Image Scaling within Limits (max height, max width) - dblack

This is a much cleaner way to do this than the number of examples on the web. Every example I saw seemed to account for orientation - horizontal vs. vertical vs. square when looking at the input. This ignores horizontal and vertical by mapping the "long side" and "short side" and then re-mapping the variables to $h / $w at the end.
