Does anybody know what is the solution of try .. catch .. block for PHP4..? This is the fault of my web hosting that's not supporting PHP5.x and the application that I'm going to create will required this piece of code below:

PHP Code:

  //catch the exception that gets thrown if the cookie has an invalid session_key in it
try {
  if (!$fb->api_client->users_isAppAdded()) {
    $fb->redirect($fb->get_add_url());
  }
} catch (Exception $ex) {
  //this will clear cookies for your application and redirect them to a login prompt
  $fb->set_user(null, null);
  $fb->redirect($appcallbackurl);
}

does anybody know how can I convert this into PHP4 style..?

thx a lot!

Here's the error message:

Code:

No try/catch on PHP 4. I don't know what your functions are or what they return, but from what's there, I'd do this:

PHP Code:

  //catch the exception that gets thrown if the cookie has an invalid session_key in it
if (!$fb->api_client->users_isAppAdded()) {
  $fb->redirect($fb->get_add_url());
} else {
  //this will clear cookies for your application and redirect them to a login prompt
  $fb->set_user(null, null);
  $fb->redirect($appcallbackurl);
}

Also, given the host thread, I'd suggest getting one of the recommended hosts.

Well, I don't have 37 lines of code so I don't know what could be wrong. If you show me the first 37 lines of fb.php, then I might be able to help more.
