PHP在对象数组中添加对象

<?php
class Product {
    public $name;
    public $price;

    public function __construct($name, $price) {
        $this->name = $name;
        $this->price = $price;
    }

    public function display() {
        echo "Product: {$this->name}, Price: {$this->price}\n";
    }
}

// 创建一个空的对象数组
$productArray = [];

// 创建一些产品对象
$product1 = new Product("Laptop", 999.99);
$product2 = new Product("Smartphone", 499.99);

// 向数组中添加对象
$productArray[] = $product1;
$productArray[] = $product2;

// 遍历数组并显示每个产品
foreach ($productArray as $product) {
    $product->display();
}
?>

$productArray = []; // 确保数组已初始化为空
