extracting specific data from json format

I have the following json format data : 

{"query":{
  "count":5,"created":"2014-12-19T15:42:41Z","lang":"en-US","results":{
    "channel":[{
      "item":{
        "forecast":{"date":"19 Dec 2014","high":"61","low":"47"}
       }},{
      "item":{
        "forecast":{"date":"20 Dec 2014","high":"60","low":"48"}
       }},{
      "item":{
        "forecast":{"date":"21 Dec 2014","high":"61","low":"44"}
       }},{
      "item":{
        "forecast":{"date":"22 Dec 2014","high":"58","low":"46"}
       }},{
      "item":{
        "forecast":{"date":"23 Dec 2014","high":"58","low":"45"}
       }}]
     }
   }
}

How can I access specific data from this format (for example only high and low), in order to insert these data in a mySQL database for instance?

Use json_decode to turn it into an array:

$array = json_decode($json_data, true);

Then, you can access the items, forecast, and high/low values:

$high = $array[1]['item']['forecast']['high'];

Put your json in a variable $str for example, than you can access the items :

$json = json_decode($str);
$res = $json->{'query'}->{'results'}->{'channel'};
foreach($res as $ch) {
    echo "High:" . $ch->{'item'}->{'forecast'}->{'high'} . "<br>";
    echo "Low:" . $ch->{'item'}->{'forecast'}->{'low'} . "<br>";
}

Assuming your json string is the variable $json:

$data = json_decode($json);
$channels = $data->query->results->channel;
foreach($channels as $channel) {
    // DO SOMETHING HERE
    die($channel["item"]["high"]);
}
