title: adding spaces between variables
body: <p>I am doing a project for class, and I need to simply put a space between the city state country and zip variables. Please help! Thank you!</p>
  
  <p>The code looks like this:</p>
  
  <pre><code>echo "&lt;p&gt;";
  echo $weather['current_observation']['display_location']['city']; 
  echo $weather['current_observation']['display_location']['state']; 
  echo $weather['current_observation']['display_location']['country']; 
  echo $weather['current_observation']['display_location']['zip']; 
  echo "&lt;/p&gt;&lt;p&gt;";
  echo $weather['current_observation']['observation_time_rfc822'];
  echo "&lt;/p&gt;&lt;p&gt;";
  echo $weather['current_observation']['weather'];
  echo "&lt;/p&gt;&lt;p&gt;";
  echo $weather['current_observation']['temperature_string'];
  echo "&lt;/p&gt;&lt;p&gt;";
  echo $weather['current_observation']['wind_string'];
  echo "&lt;/p&gt;";
  </code></pre>
