如何从URL获取JSON中的数据

Using the JSON from this URL(weather station data stored): https://dataproxy.mtcc.ie/v1.5/api/fs/weather_polygons

How do I get the data for the station "N25 Midleton Bypass"?

I can process the URL, just down know how can I echo the data?

My coding is:

  $json_string = 'https://dataproxy.mtcc.ie/v1.5/api/fs/weather_polygons';
  $jsondata = file_get_contents($json_string);
  $obj = json_decode($jsondata, true);
  var_dump($obj);

The Json data I am expecting to get is something like that:

    ["wind_speed"]=>
    float(0.9)
    ["name"]=>
    string(19) "N25 Midleton Bypass"
    ["air_temperature_legend"]=>
    string(7) "14 - 16"
    ["maximum_wind_speed"]=>
    float(2.6)
    .........

I need to get the "0.9", "14 - 16", "2.6" to save into my weather database. Thanks!
