{
status: 0,
message: "query ok",
result: {
elements: [
{
from: {
lat: 37.05983,
lng: 114.46816
},
to: {
lat: 37.069569,
lng: 114.493048
},
distance: 3369,
duration: 536
}
]
}
}
我只想拿到 distance 数据
php内置json编码和解析函数
$response=file_get_contents('https://apis.map.qq.com/ws/location/v1/ip?ip=120.239.177.236&key=申请的QQ地图密钥');//把字符串解析为数组，第二个参数默认false，解析为对象
$json = json_decode($response,true);
echo $json['location']['lng'];
echo $json['location']['lat'];
//把数组编码成字符串输出,第二个参数为不编码unicode字符(汉字就属于unicode，不编码则原样显示，编码后为 \uxxxx 的格式)
echo json_encode($json,JSON_UNESCAPED_UNICODE);
