How to use ORDER BY for a data that does not come from db? ex:

$query = $mysql->query("SELECT * FROM db_aux ;");
while($row = $query->fetch_array())
{
    $url = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=";
    $url .= $row['cep_local']."&destinations=".$row['cep_user'];
    $url .= "&language=pt&mode=car&key=AIzaSyDL6_dJ-Mbi_03_g6lHhWibxY22Z2UeYZQ";
    $json = file_get_contents($url);
    $json_data = json_decode($json, true);  
}

I want to order by this data that comes from the consultation json, DESC

 $json_data['rows'][0]['elements'][0]['distance']['text'];

in his $json_data has several lines? as would be an example of the $json_data???

{ "destination_addresses" : [ "Nova Londres, Londrina - PR, 86015-810, Brasil" ], "origin_addresses" : [ "Rio Bom - PR, 86830-000, Brasil" ], "Rows" : [ { "Elements" [ { "Distance" { "text" "111 km", "value" 111283 }, "Duration" { "text" : "1 hour 58 min.", "value" : 7101 }, "status" "OK" } ] } ], "status" "OK" }

In the example case if you have a $json_data['rows'][0]['elements'][0]['distance']['text'] my question is? how many items have these because an item does not need to be ordered!? correct

because your code isn’t wrong? shouldn’t it be on the last line $json_data[] = json_decode($json, true); ???

it’s working normal just doesn’t order

Have you seen the API documentation to see if there is no parameter you can pass in the query that returns already ordered data? Making this type of customer-side operation is quite costly at the performance level.

@Joãopedromorais in the ultma line doesn’t have to be a array?

No poblema, will be used on a panel, not directly to the customer

I do not understand very well of json but always use as this there, only that I never needed to order or receive more than 1 dice

With some modifications to your code and using the function usort if you have a sort by the desired field, example:

<?php
    $item = array(
        array('86015-810', '86830-000'),
        array('86015-820', '86840-000'),
    );
    for($i = 0; $i < count($item); $i++)
    {
        $row = $item[$i];
        $url = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=";
        $url .= "{$row[0]}&destinations={$row[1]}";
        $url .= "&language=pt&mode=car&key=AIzaSyDL6_dJ-Mbi_03_g6lHhWibxY22Z2UeYZQ";
        $json = file_get_contents($url);
        $json_data[] = json_decode($json, true);
    }


    function sort_text($a, $b) {
        $f0 = str_ireplace([' ', 'km',','], ['','','.'],
                             $a['rows'][0]['elements'][0]['distance']['text']);
        $f1 = str_ireplace([' ', 'km',','], ['','','.'], 
                             $b['rows'][0]['elements'][0]['distance']['text']);

        return $f0 > $f1;
    }

    usort($json_data, 'sort_text');

    echo '<pre>';
    print_r($json_data);
    echo '</pre>';

_{Observing: if you can use that while of the question, but, the variable has to be an array that in this case is the $json_data to store all the results and then do the ordering.}
