php - 如何将多个值传递给类？

Question

我可以像这样将一个值传递给类:

class Foo {

    public $value1;

    function __construct($var1) {
        $this->value1 = $var1;
    }
}

$foo = new Foo('value1');
print_r($foo);

如你所知，输出将是这样的:

Foo Object ( [value1] => value1 )

现在我想知道，如何将多个值传递给类？其实我想要这个输出:

Foo Object ( [value1] => value1, [value2] => value2, [value3] => value3 )

使用数组提交多个值。并添加一个输出函数，例如:

class Foo {
    public $values = array();

    function __construct($values) {
        $this->values = $values;
    }

    function output() {
        foreach ($this->values as $key => $value) {
            echo $value . "\n";
        }
    }
}

$values = ["one", "two", "three"];
$f = new Foo($values);
$f->output();
