title: What is the difference between elgg_echo and echo
body: <p>I have just started on ELGG and am pretty confused on the functionality of the Elgg_echo, Elgg.echo and echo. Therefore, when is the most appropriate time to use Elgg_echo and echo</p>
  
  <p>Hence, if I were want display the following option. Can I just use echo or do have to use elgg_echo to conform with the ELGG framework?</p>
  
  <pre><code>$dropdown = echo/elgg_echo'&lt;DIV align="center", &gt;
                      &lt;select&gt;
                          &lt;option value="A"&gt;a&lt;/option&gt;
                          &lt;option value="B"&gt;b&lt;/option&gt;
                          &lt;option value="C"&gt;c&lt;/option&gt;
                          &lt;option value="D"&gt;d&lt;/option&gt;
                      &lt;/select&gt;
                  &lt;/DIV&gt;';
  </code></pre>
  
  <p>Please help to enlighten me. I am highly confuse between elgg_echo and echo. Thanks</p>
