With no luck finding a function; here is the one I wrote:
It will evenly distribute items into a fixed amount of groups but also keeps items that were sorted close together to be in the same output groups.
<?php
function distributed_array_chunk(array $items, int $groups, bool $preserveKeys = false) {
$grouped = [];
$groupsPerItem = $groups / count($items);
$progress = 0.00;
foreach ($items as $key => $value) {
$index = floor($progress += $groupsPerItem);
if ($preserveKeys) {
$grouped[$index][$key] = $value;
}
else{
$grouped[$index][] = $value;
}
}
return $grouped;
}
?>
