Remove the line adding 'Any' at the beginning of your code and use
array_unshift() to add it at the end.
$eventList = array();
$dbh = db_open($host, $user, $password, $database);
if($dbh) {
$sthdl = db_get_event_data($dbh);
while ($row = mysql_fetch_object($sthdl)) {
$eventList[] = $row->EV_EVENT;
}
} else {
$eventList[] = "* None found *";
}
asort( $eventList );
array_unshift($eventList,'Any');
do you really need to maintain the numeric keys to the array by using
asort() instead of just sort()? If so, this may not work. You may be able to
use array_splice($input, 0, 0, array('Any')) or array_merge().
