使用SHOW FULL FIELDS获取表字段信息
php代码如下：


<"localhost","root","");
  mysql_select_db("test");
  $query = "SHOW FULL COLUMNS FROM student";
  $result = mysql_query($query);
  while($row=mysql_fetch_assoc($result)){
 print_r($row);
  }

使用mysql_fetch_field方法获取表字段信息
php代码如下：


<"localhost","root","");
  mysql_select_db("test");
  $query = "SELECT * FROM student LIMIT 1";
  $result = mysql_query($query);
  $fields = mysql_num_fields($result);
  for($count=0;$count<$fields;$count++)
  {
   $field = mysql_fetch_field($result,$count);
  print_r($field);
  }
