Answer : Yes, you can. But First argument should be an array. So, you must do it this way $_SESSION['names'] = array(); array_push($_SESSION['names'],$name); Personally I never use array_push as I see no sense in this function. And I just use $_SESSION['names'][] = $name; Try with if (!isset($_SESSION['names'])) { $_SESSION['names'] = array(); } array_push($_SESSION['names'],$name);
