度“°"字符未显示在php json_encode函数中，如何显示? [英] Degree '°' character not displaying in php json_encode function, how to display this?

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) .'}';

推荐答案

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
