JSON nested array parse via PHP - php

Question

I need to loop through and print all nested data within the "players" array and sort by "wonAmount." I can get my PHP to print out a single value, which I target, but I can't get it to work when I try the foreach loop. So instead, it prints out "array."
JSON

Answer 1

first, you need to decode the json using json_decode then you need to sort & print the player's array
$data = json_decode($json_data,true);
//extract the players from json
$players = $data["players"];
//sort players array
$wonAmount = array();
foreach ($players as $key => $row)
{
$wonAmount[$key] = $row['wonAmount'];
}
array_multisort($wonAmount, SORT_DESC, $players);
//print players data
foreach ($players as $player)
{
//add here any keys you want to print from player array
echo $player["id"];
}
