如何获取像value这样的对象：item：来自PHP Array的private

我有这样的数组：

} [“items”:”Jcart”:private]=> array(3) {
[0]=>
string(1) “3”
[1]=>
string(1) “2”
[2]=>
string(7) “ABC-123” }

如何获取PHP变量中的“items”值？

///////

完整的对象是：

object(Jcart)#1 (8) {
  ["config"]=>
  array(12) {
    ["jcartPath"]=>
    string(6) "jcart/"
    ["checkoutPath"]=>
    string(12) "checkout.PHP"
    ["item"]=>
    array(6) {
      ["id"]=>
      string(10) "my-item-id"
      ["name"]=>

      ["checkoutError"]=>
      string(34) "Your order Could not be processed!"
    }
    ["button"]=>
    array(4) {
      ["checkout"]=>
      string(0) ""
      ["paypal"]=>
      string(0) ""
      ["update"]=>
      string(0) ""
      ["empty"]=>
      string(0) ""
    }
    ["tooltip"]=>
    bool(true)
    ["decimalQtys"]=>
    bool(false)
    ["decimalPlaces"]=>
    int(1)
    ["priceFormat"]=>
    array(3) {
      ["decimals"]=>
      int(2)
      ["dec_point"]=>
      string(1) "."
      ["thousands_sep"]=>
      string(1) ","
    }
  }
  ["items":"Jcart":private]=>
  array(2) {
    [0]=>
    string(1) "3"
    [1]=>
    string(1) "2"
  }
  ["names":"Jcart":private]=>
  array(2) {
    [3]=>
    string(12) "Hockey Stick"
    [2]=>
    string(13) "Baseball Mitt"
  }
  ["prices":"Jcart":private]=>
  array(2) {
    [3]=>
    string(5) "33.25"
    [2]=>
    string(5) "19.50"
  }
  ["qtys":"Jcart":private]=>
  array(2) {
    [3]=>
    string(1) "1"
    [2]=>
    string(2) "20"
  }
  ["urls":"Jcart":private]=>
  array(2) {
    [3]=>
    string(15) "http://bing.com"
    [2]=>
    string(16) "http://yahoo.com"
  }
  ["subtotal":"Jcart":private]=>
  float(423.25)
  ["itemCount":"Jcart":private]=>
  int(21)
}

我只需要[“items”中的值：“Jcart”：private]

解决方法:

我假设您通过将对象转换为数组来实现此目的.如果是这样的话,你就不应该这样做！该属性是私有的,因为您不应该直接访问它,因为它不是公共API.对象应该有一个你应该调用的公共方法,那就是公共API.像$foo-> getItems()之类的东西.阅读文档和/或源代码.
