Three ways to work around this portion of the problem:

1. Limit the damage by placing a closing foldmarker in a comment:

e.g.

set foldtext=substitute(getline(v:foldstart),'/\\*\\\|\\*/\\\|{{{\\d\\=','','g') " }}}

2. Replace the three-open-brace portion of the regular expression with
something equivalent:

e.g.:

Change '{{{' into '[{]{{' " [ed. preventing the fold on this line]: }}}

3. Use setlocal instead of set to set up foldmethod=marker.

If you set fdm=manual, then folding is manual globally. Then in
specific filetypes you can enable fdm=marker.

E.g. I use:

" in .vimrc:
set fdm=manual
au Filetype php setl fdm=marker
