php - How to compare two 64 bit numbers -

In PHP, I have a 64 bit number that is necessary to complete the task. A second 64 bit number represents tasks that have been completed:

  $ pack_code = 100111110010000000000000001111110100111110010000000000000001011111 $ veri_code = 0000000000000000000000000000011100000000000000000100000000000000000000000000000000111110    I have two comparisons To perform and provide one percent of the tasks, the whole figure could loop through both, and found how many bits are set, but I do not know it is the fastest way?   
 
  Assuming that these are actually strings, maybe something like this:  
  $ pack_code = '1001111100100000000000000011111101001111100100000000000000011111'; $ Veri_code = '00000000000000000000000000011100000000000000000000000000000000111110'; $ Matches = array_intersect_assoc (str_split ($ pack_code), str_split ($ veri_code)); $ End_matches = array_intersect ($ matches, array (1)); $ Percent = (count ($ end_match) / 64) * 100

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.
