As I said before (http://www.dynamicdrive.com/forums/showthread.php?77239-I-NEED-HELP-MY-LOGIN-PHP-redirects-to-blank-page-logon-php&p=308559#post308559) that statement is just not true. Traq wrote a very good post (http://www.dynamicdrive.com/forums/showthread.php?74543-Updating-deprecated-code-for-MySQL-5-5&p=297484#post297484) on this topic.

Mysql_connect is deprecated, but not removed in any version of php. Mysqli_connect is actively supported and encouraged and there are no plans to remove it for the foreseeable future. The same is true for PDO. reference (http://php.net/manual/en/mysqli.overview.php) scroll down to the comparison chart for the status on each of the three main methods for connecting to MySQL using php, which includes mysql_connect.

Deadweight's response is perfectly valid.

$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Not connected');
}


$db_selected = mysql_select_db('foo', $link);
if (!$db_selected) {
die ('database is not selected');
}
