$dbh = new PDO(“MDBTools:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBq=$database;”);
//$dbh = new PDO(“pgsql:host=localhost;dbname=”,$database,””,””);
//$dbh = new PDO(“odbc:Driver=$driver;DBQ=$database”, “”, “”);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$sql = “SELECT * FROM Admc”;
