PHP array in $_SESSION - weird result -

Can anyone explain this to me?:

  if (isset ($ _ session {Pack}]} {{if_array ($ _ session ['pack'])) {foreach ($ _SESSION ['pack'] as $ pack) {// code}}}   I get:    Warning: invalid argument has been provided for foreach ()    and if I  
  dies (var_dump ($ _ session ['pack']));    find me  
  array (1) {[0] = & gt; String (2) "16"}    I'm really laughing with this one, I need to get ready for it tonight and I'm stuck with it. ..  
  
  foreach ($ _SESSION [p>    'pack'] $ pack form If you have enabled, then  $ _ session ['pack']  will be the same as  $ pack < / Code>. This can produce strange results, either make sure that register_globals are disabled or replace  $ pack  with something else.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
