title: How to get a paragraph text in php
body: <p>I want to get a paragraph data from HTML file into the php code.
  In my html file I have the following line:</p>
  <pre><code>&lt;p style=&quot;display: inline;&quot; id=&quot;symptoms&quot; name = &quot;symptoms&quot;&lt;/p&gt;
  </code></pre>
  <p>In the html file <code>document.getElementById('symptoms').value</code> gathers all the necessary data I want to use in the php code. <br>Obviously, <code>$symptoms = $_POST['symptoms'];</code> doesn't get anything. <br>How can I get it work?</p>
