1、使用mysql_fetch_field

$query=$db->query(" SELECT * FROM $tablename limit 1");

$num=mysql_num_fields($query);
for($i=0;$i {
$f_db=mysql_fetch_field($query,$i);
$showdb[]=$f_db->name;
}

2、使用show fields

$sqlr="show fields from $tablename";
$query=mysql_query($sqlr);
while($row=mysql_fetch_array($query))
{
print_r($row);
$data[]=$row['Field'];
}
