Compressed MySQL Database Connection in 1 Line.

I was compressing MySQL Database connection, then finally i compressed it in 1 line.

Please guide if any error.

Original MySQL Connection

$localhost = 'localhost';
$username = '';
$password = '';
$database = 'test';
$link = mysql_connect($localhost, $username, $password);
if (!$link) {
    die('Not connected : ' . mysql_error());
}
$db_selected = mysql_select_db('foo', $link);
if (!$db_selected) {
    die ('Can\'t use foo : ' . mysql_error());
}

Code (markup):

Compressed MySQL Connection

print (!mysql_connect('localhost', '', '')) ? die('DB Connection Error: ' . mysql_error()) : (!mysql_select_db('test')) ? die('DB Selection Error: ' . mysql_error()) : '';

1. I do not see point of this thread
2. I do not see reason why should you "compress" db connection?
