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’;

Hi,
This is actually a JavaScript/JSON question.
What you probably need is something like this:
[Javascript]
for (var key in someArray){
var theValue = someArray[key];
// do stuff
}
which is a little like PHP's:
foreach ($someArray as $key => $theValue){
}
Whit that approach you'll have the key of some array, which you will
need in your accessories-array to look up the different values.

You have to understand - PHP runs on the server, and javascript on the
client. By the time your javascript code executes, PHP has completed
its execution and terminated.
So what you have to do in your PHP code is create the javascript code to
build the array then send the javascript code to the client.

Jerry, out of curiosity, with the information you have, is there
solution that is only PHP?

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.

If you're trying to create a json string from PHP array data to send to a

If you're trying to create a PHP array or object from json data that has
been created by a javascript application:
http://uk2.php.net/manual/en/function.json-decode.php
if you're trying to create json data with javascript, or create a
javascript object from json data, try asking in a javascript newsgroup or
forum, not a php one.
If you're trying to send a string of json encoded data in response to a
client side ajax style request:
<?php
// process the request
// create the data string to send
echo $json_encoded_string;
?>
Note that generally you don't want to include any other output, and
specifically no html tags.

RTFM: <http://php.net/json_encode> (there are examples there, too!)
You would be well-advised to ignore Jerry Stuckle. The record shows that he
seldom knows what he is talking about but unfortunately compensates that
with uncalled-for rudeness.
Please follow the recommendations in

I will leave the issue of competency to those who are smarter. As to
rudeness - he is blunt, but so are you. Bluntness in and of itself is
not rude. You are not rude when you are blunt, and neither is he.
Could you both profit from a visit with Dale Carnegie to win friends and
influence people? Yes. Passing on doing so makes neither of you a lesser
person.

I've learnt far more useful stuff from Jerry's posts than from anyone else's in this
group. When he answers a question by directing the OP to another group he is always (FSVO
always) right.

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.

And you can take your self-righteous attitude and stick it where the sun
doesn't shine. That way it will be right next to your head.
In case you can't figure it out - no one here gives a damn what you
think. And no one is going to change what they do, no matter how much
you troll your crap.

It was a compliment and a defense, Jerry. Slow down on your reading.
