Description:
------------
in the manual under mysql_field_name(), http://us2.php.net/manual/en/function.mysql-field-name.php.
Example 1 is incorrect, the if statement after mysql_connect will always run true and the die statement will always run.

Reproduce code:
---------------
<?php
/* The users table consists of three fields:
 *  user_id
 *  username
 *  password.
 */
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$db_selected) {
   die('Could not set $dbname: ' . mysql_error());
}
$dbname = 'mydb';
$db_selected = mysql_select_db($dbname, $link);
if (!$db_selected) {
   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);
?> 

Expected result:
----------------
The above code would produce:

Could not set :

The if was probably suppose to check $link, not $db_selected
