Spline 3D iteraction with PHP

Hi everyone, I need help creating an interaction between my 3D model of a cube (created with Spline) and PHP .
The idea is to be able to change the color of the cube created on the spline directly from the PHP file linked to the site. It can be done? If so, how? Thank you very much! If it is not clear I explain exactly what my intentions are to be clearer.

Hi @Nico_Fossa

You cant use PHP inside Webflow, but you can make cubes. What are you trying to do with the cube?
