How can PHP developers prevent the continuous starting of new sessions for users without cookies?

When users do not have cookies enabled, PHP will start a new session for each page load, leading to unnecessary session creation and potential performance issues. To prevent this, developers can use URL rewriting to append the session ID to URLs for users without cookies. This ensures that the session is maintained across page loads without the need for cookies. 

if (!isset($_COOKIE[session_name()])) {
    session_start();
    $session_id = session_id();
    $url = $_SERVER['REQUEST_URI'];
    if (strpos($url, '?') !== false) {
        $url .= "&" . session_name() . "=" . $session_id;
    } else {
        $url .= "?" . session_name() . "=" . $session_id;
    }
    header("Location: " . $url);
    exit();
} else {
    session_start();
}
