### Plain PHP: ###
$sum = 0;
$i = 0;
$y = 0;
foreach($files as $file) {
$currentSize = filesize($file);
if($currentSize > 1024) {
if($y < 2) {

}
else if ($y > 5) {
break;
}
$y++;
$sum += $currentSize;
$i++;
}
}
$avg = $sum / $i;
echo "Average: " . $avg;
### Linq: ###
$avgL = Linq::from($files)
->select(function($x) { return filesize($x); })
->where(function($x) { return $x > 1024; })
->skip(2)
->take(4)
->average();
echo "<br/><br>Average Linq: " . $avgL;
