講解PHP類初始化功能代碼

PHP類初始化功能在php中有著重要的作用，本篇文章將詳解其相關代碼的內容。

<!--?php    class ShopProduct {        public $title = "default product";        public $producerMainName = "main name";        public $producerFirstName = "first name";        public $price = 0;        function getProducer() {            return "{$this--->producerFirstName}" . " {$this->producerMainName}";        }    $product1 = new ShopProduct();    $product1->title = "My Antonia";    $product1->producerMainName = "Cather";    $product1->producerFirstName = "Willa";    $product1->price = 5.99;    print "author: {$product1->getProducer()}";>

<!--?php      class ShopProduct {        public $title;        public $producerMainName;        public $producerFirstName;        public $price = 0;        function __construct($title,$firstName,$mainName,$price) { //構造方法            $this--->title = $title;            $this->producerFirstName = $firstName;            $this->producerMainName = $mainName;            $this->price = $price;        }        function getProducer() {            return "{$this->producerFirstName}" . " {$this->producerMainName}";        }    }    $product1 = new ShopProduct( "My Antionia", "willa", "Cather", 5.99);    print "author: {$product1->getProducer()}";>

上面把之前的初始化功能整合到類中，以減少代碼的重複。當使用new操作符建立對象時，__construct()方法會被調用。
