如何将属性类作为变量放入php中？

<?php
// 创建属性类
class Person {
    public $name;
    public $age;

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

    public function introduce() {
        echo "My name is " . $this->name . " and I am " . $this->age . " years old.";
    }
}

// 实例化属性类
$person = new Person("John", 25);

// 将属性类的属性赋值给变量
$name = $person->name;
$age = $person->age;

// 使用变量
echo $name;  // 输出：John
echo $age;   // 输出：25

// 调用属性类的方法
$person->introduce();  // 输出：My name is John and I am 25 years old.
?>
