如果我有一个包含以%符号开头的属性的对象,我该如何获取其值.

如果我使用

echo $myobject->%myproperty;

我收到一个错误

Parse error: syntax error, unexpected '%', expecting T_STRING or T_VARIABLE

我知道我不应该在变量名中使用%,但这不是我的行为而且我坚持使用它.

我有以下JSON文件作为输入,

{
  "$type": "NanoWebInterpreter.WebInputData, NanoWebInterpreter",
  "NBBList": {
    "$type": "System.Collections.Generic.List`1[[monoTNP.Common.NBB, monoTNP.Common]], mscorlib",
    "$values": [
      {

            },
            {

            {

我有一个对象，它有一个名为“Employee-ID”的属性；

我试图通过以下方式获得其价值：

echo ($row->Employee-ID);

但是 PHP 一直在说：

Undefined property: stdClass::$Employee
 Use of undefined constant ID - assumed 'ID' 

我只是有这个属性的问题，中间有“-”；我怎么解决这个问题？

谢谢
