adding spaces between variables
<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>
