Forbind PDO med Oracle-database

Kontroller, at PDO- og OCI-drivere er installeret korrekt eller ej.

Prøv med følgende kode

class PDOConnection {

    private $dbh;

    function __construct() {
        try {

            $server         = "127.0.0.1";
            $db_username    = "SYSTEM";
            $db_password    = "Oracle_1";
            $service_name   = "ORCL";
            $sid            = "ORCL";
            $port           = 1521;
            $dbtns          = "(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = $server)(PORT = $port)) (CONNECT_DATA = (SERVICE_NAME = $service_name) (SID = $sid)))";

            //$this->dbh = new PDO("mysql:host=".$server.";dbname=".dbname, $db_username, $db_password);

                PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC));
