Just a quick loop

PHP Code:


		
			
    // do percentage calculations and votes stuff

    for($i = 1; $i <= 4; $i++)

    {

        $votes[$i] = $pollinfo["option$i"."votes"];

        $totalvotes += $votes[$i];

    }

    for($i = 1; $i <= 4; $i++)

    {

        $percent[$i] = floor((($votes[$i] / $totalvotes) * 100));

    }

Anyway of making that into one loop? :) Just trying to learn new techniques - I don't use for loops often :)

Maybe I'm missing something, but...

PHP Code:


		
			
    // do percentage calculations and votes stuff 

    for($i = 1; $i <= 4; $i++) 

    { 

        $votes[$i] = $pollinfo["option$i"."votes"]; 

        $totalvotes += $votes[$i];

        $percent[$i] = floor((($votes[$i] / $totalvotes) * 100));

    }

Edit: Nope, can't see any problems there.

Yep your missing the fact that totalvotes changes on each iteration of the loop. Therefore giving a changed and inaccurate percentage on each iteration. I was wondering if there was any way around it :)

Ah, that's why it pays to look through the code!

No, I'd say two loops for that one.

2 loops, as $totalvots is only correct at teh end of the loop and you need that for the percentage.
