Personally, I think a much easier solution would be to just generate the
javascript in the page - no json overhead, no extra calls to the server
or anything else.
As for the structure of the PHP array changing - he'll have the same
problem with his javascript either way - he'll have to change the PHP
code creating the json data and/or the javascript to process it.
But either way, he still needs to know what he wants for his javascript.
