如何在PHP中返回多个值？

function getValues() {
    $value1 = 10;
    $value2 = "Hello";
    return array($value1, $value2);
}

list($result1, $result2) = getValues();
echo $result1; // 输出：10
echo $result2; // 输出：Hello

function getValues() {
    $value1 = 10;
    $value2 = "Hello";
    return array("number" => $value1, "message" => $value2);
}

$result = getValues();
echo $result["number"]; // 输出：10
echo $result["message"]; // 输出：Hello

class Result {
    public $number;
    public $message;
}

function getValues() {
    $result = new Result();
    $result->number = 10;
    $result->message = "Hello";
    return $result;
}

$result = getValues();
echo $result->number; // 输出：10
echo $result->message; // 输出：Hello
