请我做了这个代码来获取经度和纬度得到充分的经度和纬度:PHP如何使用谷歌API
$addresss = "France+mande-lieu-la-napol";
$region = "Alpes-Maritimes";
$urll = "http://maps.google.com/maps/api/geocode/json?address=$addresss&sensor=false®ion=$region";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $urll);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$response_a = json_decode($response);
var_dump ($response_a->results[0]->geometry->location->lat);
var_dump ($response_a->results[0]->geometry->location->lng);
此代码给我的结果:
float(43.546232) float(6.938309)
但实际上它必须给我
float(43.546232) float(6.938309000000004)
请问我该怎么做才能获得全部的经度?
为什么?它返回的当前值有什么问题? – thescientist
