如何从函数返回多个值？

def func():
    a = 1
    b = 2
    return a, b

result = func()
print(result)  # 输出：(1, 2)

function func() {
    var a = 1;
    var b = 2;
    return {a: a, b: b};
}

var result = func();
console.log(result);  // 输出：{a: 1, b: 2}

public class Result {
    public int a;
    public int b;
}

public Result func() {
    Result result = new Result();
    result.a = 1;
    result.b = 2;
    return result;
}

Result result = func();
System.out.println(result);  // 输出：Result{a=1, b=2}

public class Result {
    public int a;
    public int b;
}

public Result Func() {
    Result result = new Result();
    result.a = 1;
    result.b = 2;
    return result;
}

Result result = Func();
Console.WriteLine(result);  // 输出：Result { a=1, b=2 }

function func() {
    $a = 1;
    $b = 2;
    return array('a' => $a, 'b' => $b);
}

$result = func();
print_r($result);  // 输出：Array ( [a] => 1 [b] => 2 )
