所以我有以下两个sql查询，我正在尝试构建一个JSON对象以供我的Angular前端使用。
$getCompDetails = mysql_query("SELECT *
FROM competitions c
WHERE c.competitionId = '$competitionId'") or die("Couldn't select competition details");
$compDetailsArr = array();
while ($row = mysql_fetch_array($getCompDetails,MYSQL_ASSOC)){
array_push($compDetailsArr,$row);
}
$getCompUsers = mysql_query("SELECT c.userid, u.name, u.profilePic FROM competitionmembers c INNER JOIN users1 u ON u.id = c.userid WHERE competitionid = '$competitionId'") or die("Couldn't select competitions users");
$compUsersArr = array();
while ($row = mysql_fetch_array($getCompUsers,MYSQL_ASSOC)){
array_push($compUsersArr,$row);
}
$getUsrActs = mysql_query("SELECT activity_typeid, userid, time, activity_weight, activityname
FROM activity_entries
WHERE competitionid = '$competitionId'") or die("Couldn't select activities");
$userActArr = array();
while ($row = mysql_fetch_array($getUsrActs,MYSQL_ASSOC)){
array_push($userActArr,$row);
}
$compDetailsArr["users"] = $compUsersArr;
$compDetailsArr["users"]["activities"] = $userActArr;
echo json_encode($compDetailsArr);
结果如下：

这是所需的输出格式，每个用户都是单独的{}

"currentUser": 2,
"title": "Sales Hood Q1 Challenge",
"end_date": "2014-03-01 00:00:00",
"description": "This is it guys, challenge time!",
"prizeImage": "placeholder.jpg",
"prizeDescription": "Dinner for 2!",
"users": [{
"id": 2,
"name": "John Wilson",
"profilePic": "fighter-1.jpg",
"activities" = [{
"activity_typeid": 312,
"activityname": Calls
"activity_weight": 10
},
{
"activity_typeid": 312,
"activityname": Calls
"activity_weight": 10
}]
}, {
"id": 3,
"name": "Robin Christoper",
"profilePic": "fighter-3.jpg",
"activities" = [{
"activity_typeid": 312,
"activityname": Calls
"activity_weight": 10
}]
}, {
"id": 1,

"profilePic": "placeholder.jpg",

}]
}
愿意为此提供一些帮助！

不要合并数组，而是将它们嵌套：
$compDetailsArr['users'] = $compUsersArr
$json = json_encode($compDetailsArr);
答案 1 :(得分：-1)
我有同样的情况试试这个：
$compDetailsArr = $compDetailsArr;
$compDetailsArr['users'] = array();
$compDetailsArr['users'] = $compUsersArr;
$json = json_encode($compDetailsArr);
