php模仿go实现多变量返回

2021年5月25日18:40:56

环境php8.0.3

class IndexOpenController extends BaseController
{

    public function test(Request $request)
    {
        [$t1, $u1] = $this->zx();
        p($t1);
        p($u1);
    }

    public function zx()
    {
        $t = 22;
        $u = 33;
        return [$t, $u];
    }

}

 

是从PhpSpreadsheet源代码看到写法，代码方便一些

 更多返回

class IndexOpenController extends BaseController
{

    public function test(Request $request)
    {
        [$u1, $u2, $u3] = $this->zx();
        p($u1);
        p($u2);
        p($u3);
    }


    public function zx()
    {
        $t1 = 22;
        $t2 = 33;
        $t3 = 44;
        return [$t1, $t2, $t3];
    }
}

只接受部分

class IndexOpenController extends BaseController
{

    public function test(Request $request)
    {
        [$u1, $u2] = $this->zx();
        p($u1);
        p($u2);
//        p($u3);
    }


    public function zx()
    {
        $t1 = 22;
        $t2 = 33;
        $t3 = 44;
        return [$t1, $t2, $t3];
    }
}
