在运用

PHP获取表字段名通过mysql_field_name()函数来实现,该函数的语法格式如下:

string mysql_field_name ( resource $result, int $field_offset )

mysql_field_name()函数将返回指定索引的字段的名字,它的参数的描述如下。

l result:mysql_query()函数执行后返回的结果集。

l field_offset:字段的偏移量,起始值为零。

使用mysql_field_name()函数的PHP获取表字段名示例代码如下:

  1.  ?php  
  2. $connection=mysql_connect("localhost",
    "root","root") or die("连接服务器失败");  
  3. mysql_select_db("sunyang",$connection)
     or die("选择数据库失败");  
  4. $query="select * from employee";  
  5. $result=mysql_query($query) or 
    die("查询用户失败");  
  6. echo mysql_field_name($result,0);
     //输出第一个字段名  
  7. echo "br>";  
  8. echo mysql_field_name($result,1); 
    //输出第二个字段名  
  9. mysql_close($connection);   
  10. ?> 

在上面PHP获取表字段名代码中可输出第一个字段名和第二个字段名。
