mysql_field_name
    (PHP 3, PHP 4 )
mysql_field_name -- 
     Get the name of the specified field in a result
    
Description
string 
mysql_field_name ( resource result, int field_index)
     mysql_field_name() returns the name of the
     specified field index. result must be a
     valid result identifier and field_index is
     the numerical offset of the field.
    
Note: 
      field_index starts at 0.
     
      e.g. The index of the third field would actually be 2, the index
      of the fourth field would be 3 and so on.
     
     
| Example 1. mysql_field_name() example | /* The users table consists of three fields:
 *   user_id
 *   username
 *   password.
 */
$link = mysql_connect('localhost', "mysql_user", "mysql_password");
mysql_select_db($dbname, $link)
    or die("Could not set $dbname: " . mysql_error());
$res = mysql_query("select * from users", $link);
echo mysql_field_name($res, 0) . "\n";
echo mysql_field_name($res, 2); | 
 
       The above example would produce the following output:
        | 
    
     For downwards compatibility mysql_fieldname()
     can also be used. This is deprecated, however.
