[appleeaters]multiple moves and globals

im trying to make a short function to take in an array and do all the moves in it.

php Code:

Original - php Code
foreach($dir as $move) { $game=$robots->move($move); }

 
    foreach($dir as $move)
    {
            $game=$robots->move($move);
    }

it always starts and shows all the game info butnever shows any moves
btw: the $game and $robots are globals in mine but i dont see why it might be a problem

[appleeaters]RE: multiple moves and globals

Is $game a global in your function as well?

php Code:

Original - php Code
function MoveSpaces($moves) { global $robots, $game; if (! is_array($moves)) $moves = array($moves); foreach ($moves as $m) { $game = $robots->move($m); } }

function MoveSpaces($moves)
{
    global $robots, $game;
    if (! is_array($moves))
        $moves = array($moves);
    foreach ($moves as $m)
    {
        $game = $robots->move($m);
    }
}

[appleeaters]RE: multiple moves and globals

Thanks it worked

but i was wondering
I did define them as globals at the top of the script

php Code:

Original - php Code
global $robots; $robots=new robots(); global $game; $game=$robots->start();

 
global $robots;
$robots=new robots();
global $game;
$game=$robots->start();

btw: i did try to do:
global $game=$robots->start();
but it always returned:
"Parse error: parse error, unexpected '=', expecting ',' or ';' in c:inetpubwwwrootrobot.php on line 6"

well anyways it didn't seem to work until i did what you said and defined it as global inside the function also.

I was wondering why it wouldnt work w/o it?
Thanks a lot :-D

Variables inside the function are treated as local unless explicitly mentioned as global.
