一定范围内根据关键词获取经纬度

为了解决根据关键词获取经纬度，找了半天的地图平台的api都没发现，只能退而求其次，找到了高德的周边搜索，从里面获取了一个能请求在一定范围内的关键词搜索

$content = file_get_contents('http://restapi.amap.com/v3/place/around?key=你的key&page=1&radius=5000&offset=10&keywords=%E5%9B%BD%E9%99%85%E8%8A%B1%E5%9B%AD%E5%9F%8E&location=118.387716%2C24.956172&s=rsv3&rf=h5&utm_source=litemap&callback=jsonp3');
$content = ltrim($content, 'jsonp3(');
$content = rtrim($content, ')');
print_r(json_decode($content,true));

请求地址解析：

http://restapi.amap.com/v3/place/around?
key= 高德平台的key
&page=1
&radius=5000   //中心点多远
&offset=10
&keywords= 关键词
&location=118.387716,24.956172 //中心点
&s=rsv3&rf=h5&utm_source=litemap&callback=jsonp3
