度“°"字符未显示在php json_encode函数中，如何显示?
问题描述：
我像这样传递php数组
I pass php array like
[sit_latitude] => 20° 23.298' N
在json_encode()内部；输出就像，
inside json_encode(); and output is like,
{"sit_latitude":null}
显示为空，如何解决?
it's display null, how to resolve this?
我的代码段
...
$stmt->bindParam("id", $_GET[id]);
$stmt->execute();
$employee = $stmt->fetchObject();
$dbh = null;
echo '{"item":'. json_encode($employee) .'}';
答
我尝试并成功的方法有点奇怪，但是可以解决，所以让我与您分享.
what i tried and succeed was bit strange but worked , so let me share it with you.
$latitude = json_encode(utf8_encode($emplyoee['sit_latitude']));
$longitude = json_encode(utf8_encode($employee['sit_longitude']));
$emplyoee['sit_latitude'] = $latitude;
$emplyoee['sit_longitude'] = $longitude;
现在通过
echo '{"item":'. json_encode($employee) .'}';
这将解决您的问题
