将JSON字符串转换为对象的问题

Question

拉出curl请求后，我得到的响应没有错误。我的问题是访问数组数据。

var_dump（$ json）我得到JSON数据。我将数组数据设置为带有索引的$ variable，但仍然出现错误。

JSON数据

array(2) { ["meta"]=> array(1) { ["total_listings"]=> int(5994) } ["data"]=> array(1) { ["listings"]=> array(3) { [0]=> array(33) { ["id"]=> int(47603) ["name"]=> string(8) "The Crop" ["slug"]=> string(8) "the-crop" ["state"]=> string(2) "CA" ["city"]=> string(11) "Bakersfield" ["type"]=> string(10) "dispensary" ["wmid"]=> int(155018451) ["latitude"]=> float(35.414963) ["longitude"]=> float(-119.056766) ["web_url"]=> string(42) "https://weedmaps.com/dispensaries/the-crop" ["package_level"]=> string(12) "listing_plus" ["feature_order"]=> int(1) ["ranking"]=> float(4.9763046192414) ["rating"]=> float(4.9826867247295) ["reviews_count"]=> int(3789) ["avatar_image"]=> array(2) { ["small_url"]=> string(124) "https://images.weedmaps.com/dispensaries/000/047/603/avatar/square_fill/1546807008-B60BEF19-5F08-48E1-832E-B206B990BC96.jpeg" ["original_url"]=> string(121) "https://images.weedmaps.com/dispensaries/000/047/603/avatar/original/1546807008-B60BEF19-5F08-48E1-832E-B206B990BC96.jpeg" } ["license_type"]=> string(7) "medical" ["address"]=> string(13) "5950 State Rd" ["distance"]=> NULL ["zip_code"]=> string(5) "93308" ["timezone"]=> string(19) "America/Los_Angeles" ["intro_body"]=> string(352) "

["static_map_url"]=> string(82) "https://staticmap.weedmaps.com/static_map/13/35.414963/-119.056766/402/147/map.png" ["open_now"]=> bool(false) ["closes_in"]=> NULL ["todays_hours_str"]=> string(6) "Closed" ["min_age"]=> int(18) ["menu_items_count"]=> int(113) ["verified_menu_items_count"]=> int(78) ["endorsement_badge_count"]=> int(36) ["is_published"]=> bool(true) ["online_ordering"]=> array(2) { ["enabled_for_pickup"]=> bool(false) ["enabled_for_delivery"]=> bool(false) } ["retailer_services"]=> array(1) { [0]=> string(10) "storefront" } }

我的代码

$json = json_decode($response, true);

var_dump($json);

foreach($json['listings'] as $dis){

$dispensary_name = $dis['name'];
//$dispensary_state = $dis['state'];
//$dispensary_city = $dis['city'];

echo "<p>". $dispensary_name ."</p>";
}

我希望从查看JSON数据的回声中显示“ The Crop ”。但是我当前收到此错误：为foreach（）提供了无效的参数
