Answer 1

尝试这个

<?php
 mysql_query("SELECT * FROM page where page_id = '$page_id'") or die(mysql_error());

while($land = mysql_fetch_array($resultxx)){

$land =$land['land'];
$landarray = explode(",",$land);
$count = count($landarray);
echo "<select>";
for($i=0;$i<$count;$i++){
echo '<option value='.$landarray[$i].'>'.$landarray[$i].'</option>';
}
echo "</select>";
}

?>
