Hi, I've made  a function to split an array into chunks based on columns wanted. For example:

<?php $a = array(1,2,3,4,5,6,7,8); ?>

goal (say, for 3 columns):

<?php
array(
   array(1,2,3),
   array(4,5,6),
   array(7,8)
);
?>

<?php
function get_array_columns($array, $columns){
        
        $columns_map = array();
        for($i=0; $i<$columns; $i++){ $columns_map[] = 0; }//init columns
        
        //create map
        $count = count($array);
        $position = 0;
        while($count > 0){
            $columns_map[$position]++;
            $position = ($position < $columns-1) ? ++$position : 0;
            $count--;
        }

        //chunk the array based on map
        $chunked = array();
        foreach($columns_map as $map){
            $chunked[] = array_splice($array,0,$map);
        }
        
        return $chunked;
    }//end get_array_columns
?>
