              [3] =&gt; 137732801
          )
  )
  </code></pre>
  
  <p>This is the result from:</p>
  
  <pre><code>foreach($value as $val){
    echo '&lt;pre&gt;';
    print_r($value);
    echo '&lt;/pre&gt;';
          }
  </code></pre>
  
  <p>How can sum the total number of keys per Array?</p>
  
  <p>Array = 5</p>
  
  <p>Array = 6</p>
