PHP调用百度天气接口API

//百度天气接口api
$location = "北京";  //地区
$ak = "5slgyqgdenn7sy7pw29iuvrz"; //秘钥，需要申请，百度为了防止频繁请求
$weatherurl = "http://api.map.baidu.com/telematics/v3/weather?location=$location&output=json&ak=$ak";   
$ch = curl_init($weatherurl) ;
curl_setopt($ch, curlopt_returntransfer, true); // 获取数据返回
curl_setopt($ch, curlopt_binarytransfer, true); // 在启用 curlopt_returntransfer 时候将获取数据返回
$result = curl_exec($ch);
echo $result;
