PHP类初始化功能在php中有着重要的作用，本篇文章将详解其相关代码的内容。
<!--?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) { //构造方法
$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集成到类中，以减少代码的重复。当使用new操作符创建对象时，__construct()方法会被调用。
