You would need to do something like the following using a simple pagination function on an array.
<?php
$array = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16];
for($i = 1; $i < 5; $i++){
$utility = new Utility();
$utility->getItems($i, $array);
echo '<br/>';
}
class Utility{
public function getItems($index, $array, $count = 4){
$min = ($index - 1) * $count;
$max = $index * $count;
for($k = $min; $k < $max; $k++){
echo $array[$k] . ' ';
}
}
}
?>
