Do you mean something like this?
// Add the unsubscribers to an array
$unsubs = array();
foreach($unsubscribers->response->Results as $entry2) {
$unsubs[] = $entry2->EmailAddress;
}
// Loop through the subscribers
foreach($result->response->Results as $entry) {
echo '<tr class="'. $entry->EmailAddress.'">';
echo '<td>'. $entry->EmailAddress.'</td>';
echo '<td></td><td>';
// If the subscriber is in our unsubscriber array, output the email again
if(in_array($entry->EmailAddress, $unsubs)) {
echo $entry->EmailAddress;
}
echo '</td><td></td>';
echo '<td></td>';
echo '<td></td>';
echo '</tr>';
}
It will only output the email in the second column if that subscriber is also in the unsubscribers array
