require_once ("BaseDBAccess.php");
 
 
$driver = "pgsql";
$host = "localhost";
$databasename ="base";
$login = "postgres";
$pass = "admin";
 
 
$dbConnectionParameters = array(	"driver" => $driver,
									"host" => $host,
									"databasename" => $databasename,
									"login" => $login,
									"pass" => $pass								
								);
$pgDBConn = new PostgresqlDBAccess();
$a = $pgDBConn->OpenDBConnection($dbConnectionParameters);

je pense que je suis presque mais si vous pouver m'apporter des conseils
remarques : les drivers au nieavu du serveurs sont tous activés php_pdo_pgsql et php_pdo
merci
