php和mysql的小问题！！急求解！！

谢谢，我搞定了！
$query = "show columns from kris_posts like 'arrange'";
$result = mysql_db_query($dbname,$query);
$enumfirst = mysql_result($result,0,"type");
$enumlen = strlen($enumfirst);
$enumneed = $enumlen - 7;
$enumsecend = substr($enumfirst,6,$enumneed);
$enumthird = substr($enumsecend,0,-1);
$enum = explode("','",$enumthird);
for($i=0;$i<count($enum);$i++){
echo $enum[$i]."<br>";
}
