title: php include number in string
body: <p>I have a simple PHP foreach loop to populate a 'select' code with options.  The result is not as expected.</p>
  <pre><code>$i = 1;
  foreach ($geo_area as $area) {
     echo '&lt;option value=' . $i++ . '&gt;' . $area . '&lt;/option&gt;';
  }
  </code></pre>
  <p>The result is:</p>
  <pre><code>&lt;option value=&quot;0&quot;&gt;World&lt;/option&gt;
  &lt;option value=&quot;0&quot;&gt;Europe&lt;/option&gt;
  &lt;option value=&quot;0&quot;&gt;Scandinavia&lt;/option&gt;
  &lt;option value=&quot;0&quot;&gt;East Europe&lt;/option&gt;
  </code></pre>
  <p>What am I doing wrong?</p>
