Question

can anyone tell me what could cause this error “Fatal error: Class PDO not found”

when I call the singleton class like this: $db = db::krijgInstantie();

I use an mvc design and this error is weird, because I use the same code for another site

public static function krijgInstantie()
    {
        if (!self::$instantie)
        {
            $config = config::krijgInstantie();
            $db_type = $config->config_waarden['database']['db_type'];
            $hostnaam = $config->config_waarden['database']['db_hostnaam'];
            $dbnaam = $config->config_waarden['database']['db_naam'];
            $db_wachtwoord = $config->config_waarden['database']['db_wachtwoord'];
            $db_gebruikersnaam = $config->config_waarden['database']['db_gebruikersnaam'];
            $db_poort = $config->config_waarden['database']['db_poort'];

        self::$instantie = new PDO("$db_type:host=$hostnaam;port=$db_poort;dbname=$dbnaam",$db_gebruikersnaam, $db_wachtwoord);
            self::$instantie-> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        }
        return self::$instantie;
    }

thanks, Richard

Your PHP installation is missing the PDO module. Check your PHP.ini.
