【问题描述】：
我收到了 Json 格式的谷歌回复。当我解码并打印输出时，它工作得很好。像这样
print_r($output);
但是当我尝试访问数组的单个参数时，它不起作用。
print_r($output->results[0]->geometry->location->lat);
它给出了这个错误。
"message": "未定义的偏移量：0", 代码：
public function mapdata(Request $request){
$address = $request->name;
$formattedAddress = str_replace(' ','+',$address);
$response = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address='.$formattedAddress.'&sensor=true_or_false&key=APIKEY);
$output = json_decode($response);
//print_r($output);
print_r($output->results[0]->geometry->location->lat);
}
输出：
stdClass Object

【问题讨论】：
-
向我们展示
print_r($output);的结果 -
我已经添加了 print_r($output); 的结果@HTMHell
-
一步一步尝试。 print_r($output->results) 看看你得到了什么。
