    <p>I am trying to fetch an email body and send a reply to the learner based on it. But i am getting an error <code>Notice: Undefined property: stdClass::$subject</code> while executing my code. I am really lost not knowing what to do. I am posting the code below. </p> <pre><code>&lt;?php $server = '{imap.aaa.com:993/imap/ssl}INBOX'; $username = 'aaa@bbb.com'; $password = 'aaaaaa'; require_once '../swift/lib/swift_required.php'; $connection = imap_open($server,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error()); $result = imap_search($connection,'ALL'); if($result) { $output = ''; rsort($result); foreach($result as $email_number) { $overview = imap_fetch_overview($connection,$email_number,0); $message = imap_fetchbody($connection,$email_number,2); $output.= '&lt;div class="toggler '.($overview[0]-&gt;seen ? 'read' : 'unread').'"&gt;'; $output.= '&lt;span class="subject"&gt;'.$overview[0]-&gt;subject.'&lt;/span&gt; '; $output.= '&lt;span class="from"&gt;'.$overview[0]-&gt;from.'&lt;/span&gt;'; $output.= '&lt;span class="date"&gt;on '.$overview[0]-&gt;date.'&lt;/span&gt;'; $output.= '&lt;/div&gt;'; $output.= '&lt;div class="body"&gt;'.$message.'&lt;/div&gt;'; if ($message == signup) { $transport = Swift_MailTransport::newInstance(); $mailer = Swift_Mailer::newInstance($transport); $message1 = Swift_Message::newInstance('new message') -&gt;setFrom(array('aaa@aaa.com' =&gt; 'name')) -&gt;setTo(array('bbb@aaa.com')) -&gt;setBody($message); $mail = $mailer-&gt;send($message1); } } } else { echo "false return"; } ?&gt; </code></pre>

    1. COThe error message seems quite obvious, `$overview[0]->subject` is not defined :) so `var_dump($overview[0])` would be the next course of action.

    2. COBut I am wondering why define only the $overview[0]->subject. When there are more similar data like from and date?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
