This is the PDO database class/wrapper I wrote/use. Below are some usage examples:

//make database connection
$database = new database_pdo("mysql:dbname=mmIntranet;host=192.168.0.7", "loginUsername", "loginPassword");

//run an insert query with raw user input. PDO handles the data security for you
$array = array (
        ":id" => $toDoID,
        ":data" => $v,
        ":priority" => $priority
    );
$ret = $database->justquery("INSERT INTO com_toDo_listItems (toDoID,data,priority) VALUES(:id,:data,:priority)", $array);
//returns boolean true/false

//simple select query with no parameters. returns array of objects
$users = $database->query("SELECT * FROM com_users ORDER BY userLastName ASC");
//returns array of objects or false on error

//instance where you want just the first row of results as an object instead of an array containing 1 object
$user = $database->loadFirstRow("SELECT * FROM com_users WHERE userID = :id", array(":id" => $userID));
//returns object or false on error

//instance where you want the value of the first column of the first row of your query result, useful for count queries.
$totalUsers = $database->loadResult("SELECT count(*) FROM com_users");
//returns raw value or false on error
