php百度坐标转高德坐标

php处理表里存储的坐标进行转换

基于thinkphp3.2框架写的方法

public function gaoDe() {

set_time_limit(0); //防止超时

$VillageDb=D("Village");

$field="lat,lng,villageId";

$map[‘ajkId‘]=array(‘gt‘,1);

$map[‘lat‘]=array(‘gt‘,0);

$map[‘lng‘]=array(‘gt‘,0);

$data=$VillageDb->where($map)->select();//先把坐标和对应的id取出来

foreach ($data as $key=>$val){

$url="http://restapi.amap.com/v3/assistant/coordinate/convert?key=1030d03e5fa1aa9337ed6b92e43b7feb&locations=".$val[‘lat‘].",".$val[‘lng‘]."&coordsys=baidu"; //高德的key和接口转换地址

$data1=  json_decode(file_get_contents($url)); //开始转换

$location=explode(‘,‘,$data1->locations);  //取到坐标

$data=array();

$where[‘villageId‘]=$val[‘villageId‘];

$data[lat]=$location[0];

$data[lng]=$location[1];

//$result=$VillageDb->execute("update br_esf_village set lat = ".$data[$key][‘lat‘]." ,lng = ".$data[$key][‘lng‘]." where villageId=".$data[$key][‘villageId‘]."");

//if(!$result){$this->gaode();}

$result=$VillageDb->where($where)->save($data); // 保存数据

if(!$result){$this->gaode();} //失败的再次处理

}

}
