Configuration not being applied

[PZ01]

I added the following configuration variables to my .vimrc:

let b:phpfold_text_right_lines=1
let b:phpfold_text_percent = 0
let b:phpfold_doc_with_funcs=0        
let b:phpfold_docblocks=1

+--   12 lines: public __construct() {...} - StylesController constructor.-----------------------------------------------------------------------------------------------

  4 +--   27 lines: public updateSingleSizingChartException() {...}----------------------------------------------------------------------------------------------------------
  5 
  6 +--   47 lines: public updateMultiSizingChartExceptions() {...}-----------

I don't seem to see the right-alignment and the default behavior of the function + doc folding seems to be persist even if I set the doc_with_func to false.

I'm using the following version:

VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Mar 14 2018 14:26:22)

Did you set the fold method to expr like so:

" .vimrc

set foldmethod=expr

You can check what it's currently set to in your buffer by running :set foldmethod? you want that to return foldmethod=expr
