(PHP 3, PHP 4 >= 4.0.0)
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");
$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.
