now, all the numbers are on separate lines:

1

5

8

7

4

 

and getting the avg like this:

<?php

$numbers = file('ratings/' . $file . '.dat');
$count = "0";
$sum = "0";

foreach ($numbers as $line) {
$count++;
$sum = $sum+$line;

}

$avg = $sum/$count;


print "$avg";
?>

 

i'm sure ther's a better way, but this is how i got it.... any better ways are welcome :)
