获取受保护对象中的字符串 [英] Get string within protected object

问题描述

我正在尝试让该对象内部的字符串"this info"被称为$object，但是数据受到保护，如何访问该存储袋?

I am trying to get the the string "this info" inside this object lets call it $object, but data is protected, how can I access that pocket?

    object(something)#29 (1) {
  ["_data":protected]=>
  array(10) {
    ["Id"]=>
    array(1) {
      [0]=>
      string(8) "this info"
    }
    ["SyncToken"]=>
    array(1) {
      [0]=>
      string(1) "0"
    }
    ["MetaData"]=>
    array(1) {

很明显，$object->_data给我一个错误Cannot access protected property

Obviously $object->_data gives me an errorCannot access protected property

推荐答案

如果您-或该类的编写者-希望其他人有权访问受保护或私有财产，则需要通过类本身.

If you - or the writer of the class - want other people to have access to a protected or private property, you need to provide that via a getter method in the class itself.

所以在课堂上:

public function getData()
{
  return $this->_data;
}

在您的程序中:

$object->getData();
