json在动态父级中获取子级的值
问题描述：
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.

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));
