json在动态父级中获取子级的值

Question

Using PHP. How would I get clanAbbrev from a dynamic parent where it also contains "team" : "2"? I don't need to get it from every player, I just need to search it until I find the first player on Team 2. All players on team 2 are in the same "clan" and that is all I am trying to do is to get the clan tag of team 2.

Answer 1

First of all, you need to make sure that you are converting your JSON to associative array using json_decode, as such:

json_decode($players, true)

Otherwise the keys will be data members and you will suffer. Then, implement a function like this:

function getClanAbbrevByTeam($players, $team) {
    foreach ($players as $player) {
        if ($player["team"] == $team) {
            return $player["clanAbbrev"];
        }
    }
    return false; //not found
}

The function searches for the first occurrence, assuming that a team might have a single clan abbreviation. You can call the function like this:

$clanAbbrev = getClanAbbrevByTeam(json_decode($players, true));
