Hi Thore,
You can probably get away with foldmethod=expr in large files by de-activating
it in Insert mode. I.e., add this to your after/ftplugin/php.vim:
augroup FastFold
autocmd!
autocmd InsertEnter * if &ft == 'php' | setlocal foldmethod=manual | endif
autocmd Insertleave * if &ft == 'php' | setlocal foldmethod=expr | endif
augroup end
I tried it out and it actually seems to work. Folds are re-evaluated when you
are finished inserting.
HTH,
Peter
