I dont know if anyone actually discusses home repair on this group
since it's mostly all politics now, but if anyone happens to still
discuss the intended topic, I am looking for some advice about
replacing the floor around my toilet. The floor was made of particle
board and it's gotten bad. I need to replace it around the toilet. The
toilet is loose and has been a little crooked for a long time now.

I know how to remove the toilet, but I am not sure how to fit the
floor around the flange. I plan to use treated 3/4" plywood for the
replacement. The problem is that I have always seen the flange sits ON
TOP of the floor. The plumbing is PVC so I assume the flange is glued
to the pipe. I know that can not be separated.

So, how do I get the flange ON TOP of the floor? The only thing I can
think, is to install it in halves and shove it under the flange. I
suppose this would work, but I'd like to avoid having a seam in the
plywood right under the toilet, especially since I cant add some 2x4
framing under it, with the flange in the middle.

Is there another way to do this?
