<?php
$lc = sizeof($list);
for ($i = 0; $i < ( ($lc % 3 == 0) ? $lc : ($lc - ($lc % 3) + 3) ); $i = $i + 3) { // This loop defines the group you're in, $i will always be divisible by 3.
  for ($si = 0; $si < ( ($i + 3 < $lc) ? 3 : ($lc - $i) ); $si++) // Determine which item is next in this group.
    $a[] = list[$i + $si];
  $groups[] = $a;
