title: Get data from JSON file with PHP
body: <p>I'm trying to get data from the following JSON file using PHP. I specifically want "temperatureMin" and "temperatureMax".</p>
  
  <p>It's probably really simple, but I have no idea how to do this. I'm stuck on what to do after file_get_contents("file.json"). Some help would be greatly appreciated!</p>
