I've been working on an all-purpose PHP front-end that also includes a Magelo-like interface to view characters' inventories, stats, and the like.
I designed it to look a lot like the default EQ UI (and even extracted a lot of images from the tga files). It also doesn't load item information on page load like the Magelo clone, rather it opens them up in a new window. Another thought I had was to open the item stats in an iframe in the same page page, but I'm still working on more functionality (including base stats, AC & attack calculations, stat caps, and a listing of all stat modifiers) before I do that.
Right now, it is somewhat tied in to the whole package I'm putting together, but it shouldn't be to difficult to move the code around and make it separate.
You can check it out here:
An all-purpose PHP-based tool ("custom")
It is under the folder "inventory".
I'm not the best PHP coder in the world, so I'm sure there are quite a few opportunities to clean up the code.
