PHP Best mysql_type?

[Mountain Water]

  $sql = "SELECT pm FROM users WHERE id = '{$_SESSION['user_id']}'
		"; 
$result = mysql_query($sql) or die (mysql_error()); 
$num = mysql_num_rows($result);

 

$num['pm'] is data type ENUM('1','0')

 

Which mysql_fetch_____ is  the best option and best performance to just grab 1 or 0 from data

 

$num = mysql_num_rows($result);
if ($num['pm'] == "1") {
showpm();
}else {
echo "";
}

they are all they same I believe, they just change which format the data is saved in (an object, associative array, numeric array, etc.)
