Own Php code not working anymore

I use some PHP code to display some more info on an event page.
Since the last update this does not work anymore: no specific info on attendees is displayed. No name, no booking spaces, no booking comment. Has something changed?

My code:
<?php
/* @var $EM_Event EM_Event */
$people = array();
$mail_string=””;
$EM_Bookings = $EM_Event->get_bookings();
if( count($EM_Bookings->bookings) > 0 ){
?>
<table cellpadding=”0″ cellspacing=”0″ ><thead><tr><th>Nr.</th><th width=”195″>Naam</th><th width=”50″>Aantal</th><th>Opmerking</th></tr></thead><tbody>
<?php
$counter = 1;
echo ‘‘.Deelnemers.’‘;
foreach( $EM_Bookings as $EM_Booking){
if($EM_Booking->status == 1 ){
$people[] = $EM_Booking->get_person()->ID;
echo ‘<tr valign=”top”><td>’. $counter . ‘</td>
<td> get_person()->user_email. ‘”> ‘. $EM_Booking->get_person()->get_name() . ‘</td>
<td>’. $EM_Booking->get_spaces() .’ </td><td> ‘ . $EM_Booking->booking_comment. ‘ </td></tr>’;
$mail_string = $mail_string.$EM_Booking->get_person()->user_email.”, “;
$counter++;
}
}
?>
</tbody></table>
<?php
echo ‘<i>Wil je iemand een mail sturen, klik dan op zijn naam. Als je een mail naar alle deelnemers wil sturen, klik dan ‘;
echo “name} ({$EM_Event->event_start_date})’><b>HIER.</b>“;
echo ‘</i>’;
?>

<?php
}
