if i remember 4th grade math class correctly...

$total = 0;
$count = 0;

// get each of the numbers
foreach($array_of_the_numbers as $key => $value)
        $total += $array_of_the_numbers[$key];

// wow, that's a toughie!
$average = $total / $count;

// then you could make it pretty
$pretty_average = number_format($average, 1);

booyah. :)

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?
