Thank you for the response:
The version I am working on for development is 5.5.36 as on Mac OSX Yosemite (Apache with php module enabled);
to be passed by reference or value.
var sample = 'help';
var test = function()
test() //// produces an alert dialog: "help" in a browser.
That is not the case in php,
As I understand it, in php
$sample = 'help';
$_test = function($a)
$_test($sample) // prints "help"
So I am going to have to struggle a bit to shake this one out.
One of my main aims is to be able to recurse over multidimensional arrays and supply
a user defined function with a record of the progress: so, the self:$_localParams array.
The addPath element will be available to the user defined function to produce the branch
of the array that a search parameter is looking for. So It will be called in much the same
way as in my original code sample.
Thank you for time and attention
