get name of max var

[Anon]

Hi!

I use max() to determine the most common answer of a poll question... That gets the highest number of votes. I want to determine which var was max...

this is what I do (not actual code):
$var1 = 12;
$var2 = 5;
$var3 = 10;
$var4 = 7;
$pop = max($var1, $var2, $var3, $var4);

$pop will return 12
Is there a way to find out that $var1 was the max var?

Thanks
Vasse

why not just put all of your $var's into an array?

<?
$var = array (12, 5, 10, 7);
$pop = max ($var);
?>

$pop equals 12
