我想要拿到我的目录。多维数组中的信息- PHP

$myArray = array(
    "fruit" => array(
        "apple" => array(
            "color" => "red",
            "taste" => "sweet"
        ),
        "banana" => array(
            "color" => "yellow",
            "taste" => "sweet"
        )
    ),
    "vegetable" => array(
        "carrot" => array(
            "color" => "orange",
            "taste" => "crunchy"
        ),
        "spinach" => array(
            "color" => "green",
            "taste" => "bitter"
        )
    )
);

// 访问水果的颜色
$fruitColor = $myArray["fruit"]["apple"]["color"]; // 输出：red

// 访问蔬菜的味道
$vegetableTaste = $myArray["vegetable"]["spinach"]["taste"]; // 输出：bitter
