JSON - How to merge nested object inside array in php

Question

Hi I want to put json nested object with this format:

[{"lat":-6.92015,"lon":107.67024,"value":0.1},{"lat":-6.88283,"lon":107.60149,"value":0.1},..]

into this json array :

{"max": 30, "data": [...]}

and will result in this format :

{"max": 30, "data": [{"lat":-6.92015,"lon":107.67024,"value":0.1},...]}

my current code :

$data[] = array(lat=>(float)$row["geo_lat"], lon=>(float)$row["geo_long"], value=>1);
$post_data = json_encode(array('max' => 30, 'data' => $data));
echo $post_data;

How I can do that? Thanks

Check this:

$array = json_decode('[{"lat":-6.92015,"lon":107.67024,"value":0.1},{"lat":-6.88283,"lon":107.60149,"value":0.1}]');

print_r($array);

$final_array = array('max'=>30,'data'=>$array);
print_r($final_array);

$output = json_encode($final_array);
print $output;

Code in action: eval.in
