Method toggle

  public function toggle (string $prop, int|bool $toggle = 42): self; 

Toggler for the boolean properties. Toggles particular runtime option on/off.

• @prop - Accepts valid INI config TOGGLER string. - quotes_only
  - tags_expand
  - attr_expand
  - enforce_cdata
  - backend_notgood
  - avoid_phpxml
  - tongue_generator
  - source_squeeze
  - null_expose
  - silent_errors
  - error_logging

  STALL Config Property cannot be altered with this method.
  You may want to use public method set for that.

• @toggle - Valid values are boolean true or false. Default is integer 42 which results in setting the opposite of current runtime value. Accepts integers 1 or 0 beside boolean values. Anything other than 1 or true will be converted to false, unless, as already mentioned, value is - 42 .

Returns Funcdown object so that method chaining can occur if plausable.

  $funcdown-> toggle ('error_logging', false);
