Я нашел простую оболочку базы данных на http://www.phpclasses.org/browse/file/24355.html, но не могу выбрать строки

Ниже приведен код для извлечения строк:
включает 'DBConnect.php';
DBConnect::Prepare("127.0.0.1","myUser","myPass","mySchema");
$mysql_result = DBConnect::Select("SELECT * FROM myTable");
while($row = DBConnect::getRow($mysql_result)){
