group elements inside a json - php

Question

I'm trying to make a json that looks like this:
{
"data": {
"error_message": "",
"data": {
"person": [
[
{
"name": "teset1",
"image": "http://test.co.il/test/icons/billadress.png"
},
{
"name": "test2",
"image": "http://test.co.il/test/icons/email.png"
},
{
"name": "test3",
"image": "http://test.co.il/test/icons/homeicon.png"
}
],
[
{
"name": "a",
"image": "http://test.co.il/shay/keykit/icons/billadress.png"
},
{
"name": "b",
"image": "http://test.co.il/shay/keykit/icons/email.png"
},
{
"name": "c",
"image": "http://dvns.co.il/shay/keykit/icons/homeicon.png"
}
],
[
{
"name": "a",
"image": "http://test.co.il/test/icons/billadress.png"
},
{
"name": "b",
"image": "http://test.co.il/test/icons/email.png"
},
{
"name": "c",
"image": "http://dvns.co.il/test/icons/homeicon.png"
}
],
]
}
},
}
This is the code i'm using after i'm getting the name & image from the mysql query:
$response = $this->_db->query($query)->result_array();
$icons_results = array();
$obj = new stdclass();
foreach ($response as $key => $response) {
$icons_model = new icons_model();
$icons_model->init($response);
$obj->families[] = $icons_model;
}
return $obj;
SO .. this is what i'm getting:
{
"data": {
"families": [
{
"id": "1",
"name": "a",
"image_url": "http://test.co.il/shay/keykit/icons/billadress.png"
},
{
"id": "2",
"name": "b",
"image_url": "http://test.co.il/shay/keykit/icons/email.png"
},
{
"id": "3",
"name": "c",
"image_url": "http://test.co.il/test/icons/homeicon.png"
},
{
"id": "6",
"name": "f",
"image_url": "http://test.co.il/test/icons/homeicon.png"
},
{
"id": "4",
"name": "d",
"image_url": "http://test.co.il/test/icons/billadress.png"
},
{
"id": "5",
"name": "e",
"image_url": "http://test.co.il/test/icons/billadres2323s.png"
},
and do on.
How to i make that every three object will be in a group? (like the first example)

Answer 1

Try this:
foreach ($response as $key => $response) {
$icons_model = new icons_model();
$icons_model->init($response);
$obj->families[(int)($key / 3)][] = $icons_model;
}
