[PHP] Array assistance

2004-07-27 Thread Alex Hogan 
Hi All,
 
I have a page where I'm collecting answers from a series of questions.
The questions are entered into the array one at a time so I can keep
track of paging.
$arans  =   array($_POST);
$_SESSION['arans'][$pageid] = $arans;

Then I want to check the sum of the array for scoring purposes. However
I have to get to the key that has the values for the scores.

for($i = 1; $i = 10; $i++){
print_r($_SESSION['arans'][$i]);
printbr;
}

Give me this...
 
Array ( [0] = Array ( [mc] = 0 [Submit] = Submit ) ) 
Array ( [0] = Array ( [mc] = 10 [Submit] = Submit ) ) 
Array ( [0] = Array ( [mc] = 0 [Submit] = Submit ) ) 
Array ( [0] = Array ( [truefalse] = 10 [Submit] = Submit ) ) 
Array ( [0] = Array ( [mc] = 0 [Submit] = Submit ) ) 
Array ( [0] = Array ( [truefalse] = 10 [Submit] = Submit ) ) 
Array ( [0] = Array ( [mc] = 0 [Submit] = Submit ) ) 
Array ( [0] = Array ( [truefalse] = 10 [Submit] = Submit ) ) 
Array ( [0] = Array ( [mc] = 10 [Submit] = Submit ) ) 
Array ( [0] = Array ( [truefalse] = 10 [Submit] = Submit ) )

Ten separate arrays with an array at 0 that has the data I'm after.
This is where I'm getting stuck.  How can I get to the keys that are
either 'mc' or 'truefalse' and sum them?

Thanks,

alex hogan

I would simply build the array more specifically, so that it doesnt
include things you dont want.

foreach my man
http://us2.php.net/foreach

foreach ($_SESSION['arans'] as $arans) {
$truefalse += $arans['truefalse'];
$mc += $arans['mc'];
}
