Just a quick loop

[Dean C]

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

[John]

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.
