需要在JSON输出中仅显示数组值

Question

如何在PHP中显示JSON中的数组值

我在PHP代码下面使用

echo '{"aaData":'.json_encode($user_details).'}';

它返回输出

{"aaData": [
    {"id":"31","name":"Elankeeran","email":"ekeeran@yahoo.com","activated":"0","phone":""}
]}

但我需要JSON输出，如下所示

{"aaData": [
    {"31","Elankeeran","ekeeran@yahoo.com","0","1234"}
]}

任何人请帮忙。

Answer 1

$rows = array();
foreach ($user_details as $row) {
  $rows[] = array_values((array)$row);
}

echo json_encode(array('aaData'=> $rows));

输出：

{"aaData": [
    ["31","Elankeeran","test@yahoo.com","0","1234"],
    ["33","Elan","test@gmail.com","1",""]
]}

Answer 2

echo '{"aaData":'.json_encode(array_values($user_details)).'}';

应该这样做

Answer 3

您的PHP已经生成了有效的JSON。要从JavaScript访问其中的项目，请使用以下模式：

obj.aaData[0].name;
// Elankeeran

obj.aaData[0].email;
// email@yahoo.com
