My code looks nicer. 

import kurt
kurt.ScratchProjectFile("project.sb").info["thumbnail"].save("thumbnail.png")

Does anybody know it in PHP? (i.e. to get it as a PNG or something?)

I don't think anyone's written a .sb parser in PHP. If your host supports Python, you could always execute a Python script using PHP's "exec". 

I wrote one once upon a time. I could quickly translate my JavaScript one to PHP...

Here. It accepts a (local) file path in the "filename" request argument and outputs a thumbnail PNG.

Thanks. Testing it out.
