我正在使用 google geocode api，它创建了一个我不知道如何使用的数组。我需要从这个数组中提取特定元素。特别是数组中的最后一个纬度和经度。

{
    "results": [
        {
            "address_components": [
                {
                    "long_name": "1600",
                    "short_name": "1600",
                    "types": [
                        "street_number"
                    ]
                },
                {
                    "long_name": "President's Park",
                    "short_name": "President's Park",
                    "types": [
                        "establishment"
                    ]
                },
                {
                    "long_name": "Pennsylvania Avenue Northwest",
                    "short_name": "Pennsylvania Ave NW",
                    "types": [
                        "route"
                    ]
                },
                {
                    "long_name": "Washington",

                },
                {

                    ]
                },
                {
                    "long_name": "United States",

                    ]
                }
            ],
            "formatted_address": "1600 Pennsylvania Avenue Northwest, President's Park, Washington, DC 20500, USA",
            "geometry": {
                "location": {

                },

                "viewport": {
                    "northeast": {

            "types": [
                "street_address"
            ]
        }
    ],
    "status": "OK"
}


Array
(
    [latitude] => -77.0365123
    [longitude] => 38.8978378
    [location_type] => ROOFTOP
)

由于您有 JSON 格式的结果，并且结构现在更清晰，格式更清晰，因此您可以通过以下方式获得该结果中的 lat 或 lng 值

$object=json_decode($json);
$lat=$object->results[0]->geometry->location->lat; // same style for lng
echo $lat;
