[SOLVED] Counting Code, probs pretty simple

[DeanWhitehouse]

Heya once more,

 

I wrote a blackjack code a while back as some of you may remember but i am finding a bug in this function

 

<?php
function getTotal($player)
{

	$current_total = 0;

	$new_total = 0;

	//$ace_total = 0;


	foreach($player as $counting)
	{

		$current_total += $counting['value'];

	}

	foreach($player as $counting)
	{

		if($counting['value'] == 1 && $new_total < 11 && ($new_total  + 11) <= 21)
			$counting['value'] = 11;
		elseif($counting['value'] == 11 && $new_total >= 11 && $new_total + 1 <= 21)
			$counting['value'] = 1;

		$new_total += $counting['value'];

	}

	return $new_total;

}
?>

 

The function, will count the value of the cards in your hand. Now the problem, the function counts the cards in the order they are in and the problem with this is that it needs to determine whether an ace is worth 1 or 11 by counting the value of the other cards, see the problem, if it counts the ace first it will make it 11 then that can make a player bust as they then might have a 8 and a 3 with it in which it should count ace as 1.

 

Ok, hope that made sense, if not please say.

 

Any ideas how to fix this, cus i thought i had but odviously not

 

Thanks,

Blade

In the loop, if you get to an ACE, store it into a $count variable. It should be an int counting how many aces are in the hand. Then once you count up the rest of the cards, then determine how to treat an ace.

Yeah thought so, i just changed the if statements in the second one to use $current_total for the counting sums and seems to work
