*"Yeah I know it should be done with json_decode. But I don't know how to do it."*

Ok, somehow you're getting data into a variable, let's say $data

$array=json_decode($data, true);

will convert that into an array which in this case has other arrays and variables inside id

To see the whole thing print_r($array); and view source code, or echo '<pre>'; print_r($array);

So to get to the bits you want to need to traverse the array, but what you want is in one element of many in an array locations so we need to iterate through them

foreach ($array['response']['deals']['active']['locations'] as $location)
{
     echo 'id:'.$location['id'];
     echo 'lat':$location['lat'];
     //ect
}

or you could pick the first one

echo $array['response']['deals']['active']['locations'][0]['id'];
