A standard database layer will return false, and set a error code
and error message property, so the application using the class can
do something about it.
if (! $link = mysql_connect($host..) ) {
$this->error = mysql_errno();
$this->error_msg = mysql_error();
return false;
}
...
Then in the application:
if (! $dbh = $db->Connect(blah...) ) {
echo $db->error, ': ', $db->error_msg;
exit;
}
