Deleting or not showing item in php/mysql.

[iads]

I have an online calendar script that displays an ordered list of

upcoming events. The problem is that the past items are not falling

off after the event date. How do I write the script to only show

events that have not happened yet, or set the database to delete the

item all together? I believe that has something to do with

"Operations/Triggers". As far as what the script looks like, here

is a snippet:

<?php
            
            echo '<ul class="thumbnails">';
            
            for($i=0; $i<count($events); $i++) {
                $id = $events[$i]['id'];
                $date = $events[$i]['date'];
                $why = $events[$i]['why'];
                $address = $events[$i]['address'];
                $background = $events[$i]

['background'];
                $invited_friends = $events[$i]

['invited_friends'];
                
                $bg_link =

'include/graph/backgrounds/'.$GLOBALS['backgrounds'][$background]

['image'];
                
                echo '<li class="span5">';
                    echo '<div

class="event_item">';
                        echo '<a

href="event.php?id='.$id.'">';
                        if($GLOBALS

['backgrounds'][$background]['image']!='') echo '<img src="'.

$bg_link.'" style="width:110px; height:80px; float:left; margin-

right:10px; border: 1px solid #e5e5e5; margin:4px;"></a>';
                        echo '<div>';
                        if($why!='') echo

'<a href="event.php?id='.$id.'">'.$why.'</a><br>';
                        if($date!='') echo

'<b>'.$date.'</b><br>';
                        if($address!='')

echo $address.'<br>';
                        echo '</div>';
                        echo '<div

style="clear:both;"></div>';
                    echo '</div>';
                echo '</li>';
            }
            
            echo '</ul>';
            
            if(count($events)==0) echo 'No coming

events';
            ?>
