如何获得对象像值:项目:私有从PHP数组

数组是这样的:

} ["items":"Jcart":private]=> array(3) {[0] =>字符串(1)"3"[1] =>字符串(1)"2"[2] =>
字符串(7)"abc - 123 "}

如何在php变量中获得"项目"值?

///////

完整对象为:

object(Jcart)#1 (8) {

  array(12) {

  ["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]=>
