I can't seem to see a pre-built functions but here is one I just wrote in
my email client:
function average($numberArray) {
$sum = 0;
for ($i=0;$i<count($numberArray);$i++)
$sum += $numberArray[$i];
return $sum / count($numberArray);
}
echo average(array (1,2,3,4,5));
Hope this helps :)

Subject: [PHP] Average Number For Math Functions
Ok I looked at all the math functions for PHP but saw no way of returning
the average of a set of numbers - I plan on using this for a rating
system - any help?
