$tf_username = 'root';
$tf_password = '' ;

$tf_handle = mysql_connect($tf_host , $tf_username , $tf_password);

if (!$tf_handle)

Answer 1

Unless you copied your code incorrectly, your check is not going to result in what you want.

$tf_db_result = mysql_select_db($tf_dbname);
if($tf_db_result)

your selection seems fine so either you should change your code to

if(!$tf_db_result) //note the !

or restructure your code

if($tf_db_result) {
     //Do the stuff you want to do when you are connected
} else {

 //Die connection
}
