需要循环遍历一个动态大小的PHP数组

Question

I have a poker game where 2 to 5 players join the game before the start button is pressed.They are added to a players arrays array as objects containing userid and username.

I need to populate my currentUser with the player object then on a button click(call/raise/fold) move to the next in the array to give illusion of the game moving seat to seat

When the start button is clicked i set the current user to the first element in the array which works.

$thisPokergame->State['CurrentUser'] = RESET($thisPokergame->State['Players']);

then im trying this

    if($thisPokergame->State['CurrentUser'] == end($thisPokergame->State['Players']))
    {
        $thisPokergame->State['CurrentUser'] = reset($thisPokergame->State['Players']);
    }
    else{
        $thisPokergame->State['CurrentUser'] = next($thisPokergame->State['Players']);;
    }

the if works by itself e.g if its the last player in the array it set current user to the the first and so does the statement inside the else.

When i put them together i get currentuser as false and i cant see the reason. anyone have a solution or better way to do it?

Answer 1

You are having this problem because the functions you're using move the internal array pointer.

You will always get false in the else part of your conditional, because when you use end($thisPokergame->State['Players']) in the if condition, you have moved the internal array pointer to the the last element. Then in the else when you do next($thisPokergame->State['Players']), you get false because there are no more elements.

Without knowing for sure what is in CurrentUser or Players I'm not certain how this could be handled instead, but I think this might work:

$player = array_shift($thisPokergame->State['Players']);
$thisPokergame->State['Players'][] = $player;
$thisPokergame->State['CurrentUser'] = reset($thisPokergame->State['Players']);

Basically just rotate the first player in the list of players to the end of the list, and then set the current user to the new first player in the list.
