SESSION と COOKIE を使用して PHP でデータ型を管理および操作する方法

// 启动SESSION
session_start();

// 存储字符串
$_SESSION['name'] = 'John';

// 存储数组
$_SESSION['array'] = array('apple', 'banana', 'orange');

// 存储对象
class Person {
    public $name;
    public $age;
}

$person = new Person();
$person->name = 'Tom';
$person->age = 25;

$_SESSION['person'] = $person;

// 读取数据
$name = $_SESSION['name'];
$array = $_SESSION['array'];
$person = $_SESSION['person'];

// 输出数据
echo $name; // 输出：John
print_r($array); // 输出：Array ( [0] => apple [1] => banana [2] => orange )
echo $person->name; // 输出：Tom
echo $person->age; // 输出：25

// 销毁SESSION
session_unset();
session_destroy();

// 存储数据
setcookie('name', 'John', time() + 3600); // 存储字符串

$fruits = array('apple', 'banana', 'orange');
setcookie('fruits', json_encode($fruits), time() + 3600); // 存储数组

$person = new Person();
$person->name = 'Tom';
$person->age = 25;
setcookie('person', base64_encode(serialize($person)), time() + 3600); // 存储对象

// 读取数据
$name = $_COOKIE['name'];
$fruits = json_decode($_COOKIE['fruits'], true);
$person = unserialize(base64_decode($_COOKIE['person']));

// 输出数据
echo $name; // 输出：John
print_r($fruits); // 输出：Array ( [0] => apple [1] => banana [2] => orange )
echo $person->name; // 输出：Tom
echo $person->age; // 输出：25

// 删除COOKIE
setcookie('name', '', time() - 3600);
setcookie('fruits', '', time() - 3600);
setcookie('person', '', time() - 3600);
