如何在值爲對象時獲取數組內容？

Question

我有一個數組，其中包含不同的數據類型。那些是int和object。該數組如下。

Array ( 
    [isHR] => 1 
    [1] => Array ( 
    [0] => MyQuota Object ( 
     [year:private] => 2011 
     [leaveId:private] => L001 
     [employeeId:private] => 
     [NoOfDays:private] => 7.00 
     [leaveName:private] => Casual Leave 
     [Message:private] => 
    ) 
    [1] => MyQuota Object ( 
     [year:private] => 2011 
     [leaveId:private] => LTY002 
     [employeeId:private] => 
     [NoOfDays:private] => 55.00 
     [leaveName:private] => Priviledged Leave 
     [Message:private] => 
    ) 
) 
    [Length] => 8 
) 

這裏我需要獲取並設置名爲「NoOfDays：private」的數組屬性。我怎樣才能得到這個？

Answer 1

添加getter和setter方法：

class MyQuota 
{ 
    private $year; 
    private $leaveId; 
    private $employeeId; 
    private $NoOfDays; 
    private $leaveMessage; 
    private $Message; 

    /* more code */ 

    public function getNoOfDays() 
    { 
     return $this->NoOfDays; 
    } 

    public function setNoOfDays($noOfDays) 
    { 
     $this->NoOfDays = $noOfDays; 
    } 

    /* more getters and setters */ 

} 

而且，隨着你的陣列，像這樣使用：

$days = $array[0][1]->getNoOfDays(); 

Answer 2

最簡單直接的方法之一請參考此頁。 [1] http://php.net/manual/en/function.get-object-vars.php

Answer 3

您可能無權訪問對象的私有屬性。要麼讓它們公開，要麼定義getter和setter方法。

訪問公共屬性：

echo $arr[1][0]->NoOfDays
