If you get an error of this kind:

"Warning: mysql_query() [function.mysql-query]: Access denied for user
'ODBC'@'localhost' (using password: NO) in D:\Program Files\Apache Software
Foundation\Apache2.2\htdocs\login.php on line 17

Warning: mysql_query() [function.mysql-query]: A link to the server could
not be established in
D:\Program Files\Apache Software Foundation\Apache2.2\htdocs\login.php on
line 17"

It means that either your mysql conenction details are not correctly set or
the connection resource isn't accessible for your mysql functions. I suggest
you first try by replacing:

$link = mysql_pconnect('localhost', 'root', 'testing');

into:

mysql_pconnect('localhost', 'root', 'testing');
