title: If API value is empty show default value
body: <p>I want this to display <code>0</code> if the <code>nb_impressions</code> is empty</p>
  
  <pre><code>foreach ($content as $row) {
     $impressions = $row['nb_impressions'];
     print("&lt;td'&gt;$impressions&lt;/td&gt;");
  }
  </code></pre>
  
  <p>The value is from a <code>HTTP API</code> however, if the value is empty it displays as empty, how can I give these empty values <code>0</code></p>
