php - Two MySQL result sets to a nested array -


i'm having 2 tables of data "item" , "subsidiary" following structure:

item itmcod itmname

subsidiary itmcodparent itmcodchild

i need show list of items each list of subsidiaries, in json:

{    "itmcod":1,    "itmname":"bogusitem1",    "subsidiaries":    [       {          "itmcodparent":1,          "itmcodchild":15       },{          "itmcodparent":1,          "itmcodchild":16             }    ] },{    "itmcod":2,    "itmname":"bogusitem2",    "subsidiaries":    [       {          "itmcodparent":2,          "itmcodchild":17       },{          "itmcodparent":2,          "itmcodchild":18             }    ] }

how can add second result set first 1 have nested shown above. have code far:

$sql = "select itmcod, itmname item";  $item_rows = array();  while($item_row = $database->fetch_array_assoc($item_result)){     $sub_sql = "select itmcodparent, itmcodchild subsidiary subsidiary.itmcodparent = " . $item_row["itmcod"];     $sub_result = $database->query($sub_sql);     $sub_rows = array();     while($sub_row = $database->fetch_array_assoc($sub_result)){       $sub_rows[] = $sub_row;    }     $item_rows[] = $item_row; }  print json_encode($item_rows);

thanks.

just above line

$item_rows[] = $item_row;

simply add

$item_row['subsidiaries']=$sub_rows;
