Question

This script is supposed to to get a multidimensional array and iterate through the values.

The array size is 10 and each element should contain an associative array:

$games[0] => array('foo' => 'bar')
$games[1] => array('foo1' => 'bar1')
etc..

The while loop should iterate 5 times in this example. The for loop should iterate 10 times for each iteration of the while loop.

So I am expecting the echo to be:

countwhile = 5 countfor = 50 totalgames = 50

but im actually getting

countwhile = 5 countfor = 150 totalgames = 150

I believe $games array is not the problem because i have have made that call below before and have used print_r to view the contents and it is as expected.

This whole code is not in a function or class just as is on my index.php page, could the problem be to do with the variable scopes?

$totalruns = 5;  
$endindx = 10;
$startindx = 0;
$countwhile = 0;
$countfor = 0;
$totalfilesize = 0;
$totalgames = 0; 
$sizeof = 0; 

while($totalruns > 0)  
{  
     $games = $feedHandler->getGames($startindx, $endindx);  
     $sizeof = sizeof($games);  

     for($i=0; $i<$sizeof; $i++)  
     {  
          $totalfilesize += $games[$i]['swf_file_size'];
          $countfor++;  
     }  

     $startindx += 10;
     $endindx += 10;  
     $totalruns -= 1;  
     $totalgames += $sizeof;
     unset($games);  
}  

echo'<p>' . ' countwhile = ' . $countwhile . ' countfor = ' . $countfor . '</p>';

As i said in my comment $e is overwritten at each loop, so what you have in $e at the end is just the last count of elements in $games *2.
Added with ajreal issues this means results are what your code is expected to render 🙂 and I’m quite sure your last $game is not just 10 elements but 50. Quiet sure… but it’s hard to read.
