这个例子建了一个连接，用ODBC打开Access的数据库NorthWind（安装Access时带的示范）。在执行了SQL语句后，返回了RecordSet对象。例子显示了前三个字段：
$dbc = new COM("ADODB.Connection");
$dbc->Provider = "MSDASQL";
$dbc->Open("nwind");
$rs = $dbc->Execute("select * from products");
$i = 0;
while (!$rs->EOF) {
$i += 1;
$fld0 = $rs->Fields(0);
$fld1 = $rs->Fields(1);
$fld2 = $rs->Fields(2);
print "$fld0->value $fld1->value $fld2->value
";
$rs->MoveNext();
}
$rs->Close();
?>
