How to do split colors in php?

Question

PHP

How to make such an effect in PHP GD?
PS: It's not me in the photo

Answer 1

I mean ... take the blue and red channels and move them a little bit?

Answer 2

You can, of course, take the red channel in one "hand", the other two in the other, and move them relative to each other. But the whole point of anaglyph is to show the object in volume so that it can be viewed through anaglyph glasses, and such a simple filter will not do this.
