php：自定義類型的屬性

Question

我想寫下面的代碼，雖然它是錯誤的，它可能會證明最好的爲什麼我試圖做。

class myClass 
{ 
    private $name = ""; 
    private $startAddress = new myAddress(); // this is the issue 
    private $endAddress = new myAddress(); // this is the issue 
} 

我該如何做到這一點？

謝謝

Answer 1

<?php 
class myClass { 
    private $endAddress; 
    public function __construct() { 
     $this->endAddress = new myAddress(); 
    } 
} 

就拿constructor，這被稱爲每次創建新對象時的優勢。
