Database Abstraction
Well matured library: It has been continuously
developed since 2000.
Very good performance-monitoring library.
Easy to use caching functions helping to increase
performance of high traffic sites.
Full database session support: Allows for easy
creation of user systems.
Layered code makes ADODB a very fast library and
only adds a slight overhead if performing common
tasks.
Using Adodb

require('adodb.inc.php');

$dsn = 'mysql://username:pwd@localhost/dbname?persist';

$db = ADONewConnection($dsn); # no need for Connect()

$sql = "SELECT Nama FROM MHS” ;

$cset = $db->Execute($sql) ;

While (! $cset->EOF) {

}
$arr = $cset->FetchRow() ;
$nama = $arr[0] ;
Print $name. “<br />” ;
