jQuery ajax给出500内部错误

我正在尝试使用发送jquery ajax请求

jQuery.ajax({
                  method: "POST",
                  url: "some2.php",
                  data: { data: result }
                })
                  .done(function( msg ) {
                    alert( "Data Saved: " + msg );
                  });

此代码正在发送请求,localhost但在服务器上传时,则出错500 internal error

我some2.php是

";
?>

我缺少的东西请帮助我

请更换

echo "Distance From Khandar Bus Stand : ".distance($data[0], $data[1],  25.992739,76.379046 "K") . " Kilometers
";

至

echo "Distance From Khandar Bus Stand : ".distance($data[0], $data[1], 25.992739,76.379046 , "K") . " Kilometers
";

distance在单元参数之前调用函数时缺少逗号.
