3 selects?
the select also must to be dependant; example Car Brand->Car
Model->Accessories
I look guide but cannot understand how solve the problem
ARRAY BRAND
brand[01]='Brand 1';
....
brand[20]='Brand 20';
ARRAY MODEL (every brand have 3 models,total 60 models)
model[01][m01]=’model m01 of brand 1’;
model[01][m02]=’model m02 of brand 1’;
....
model[20][m59]=‘model m59 of brand 20’;
model[20][m60]=‘model m60 of brand 20’;
ARRAY ACCESSORIES (every models can to have n accessories; exmpl. m01-> 3
accessories,
m60 -> 2 access.)
accessories[m01][]=‘accessories 1 of model m01’;
accessories[m01][]=‘accessories 2 of model m01’;
accessories[m01][]=‘accessories 3 of model m01’;
……..
accessories[m60][]=‘accessories 1 of model m60’;
accessories[m60][]=‘accessories 2 of model m60’;

Not if he wants to use json. Other than that, I have no idea what he's
trying to do. But if it requires execution on the client, then
obviously not. However, if it could all be done server-side, then it
easily could.
But reading between the lines, I suspect he's using AJAX to refresh part
of a page after a search is performed. I don't know, though, and could
be way off.

YMMV.
However, as you could have noticed, this is _not_ solely a JavaScript/JSON
question, as PHP has had a *built-in* function for creating JSON from PHP
arrays for quite some time (which is a Good Thing, as it spares you all the
looping and escaping). Subscribers of cljs, for example, do not need to
know that as there are various ways to create JSON. So that question is not
off-topic here, and it is not on-topic there.
Not knowing that (or knowing where to find it to give the correct answer)
but replying with somewhat correct, yet useless information nevertheless
("somewhat" because e.g., PHP is _not_ limited to the server side as
JavaScript is _not_ limited to the client side, and there is no "javascript"
to begin with – we have been over this) does _not_ count as a competent
answer in my book, and in my experience there have been few useful comments
from Jerry but a lot of unnecessarily rude and really useless ones by
comparison. Enough for me to ignore him (with one exception) and recommend
that to others similarly mistreated, which I usually do not do. Sorry, but
that's that.

I can read just fine, Bill. And I stand by my statement.
