   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'];

  }
