Positional information

It is possible to see the precise positional and dimensional information of each item as packed. This is exposed as x,y,z co-ordinates from origin, alongside width/length/depth in the packed orientation.

z    y

Example:

<?php

    // assuming packing already took place
    foreach ($packedBoxes as $packedBox) {
        $packedItems = $packedBox->items;
        foreach ($packedItems as $packedItem) { // $packedItem->item is your own item object
            echo $packedItem->item->getDescription() .  ' was packed at co-ordinate ' ;
            echo '(' . $packedItem->x . ', ' . $packedItem->y . ', ' . $packedItem->z . ') with ';
            echo 'w' . $packedItem->width . ', l' . $packedItem->length . ', d' . $packedItem->depth;
            echo PHP_EOL;
        }
    }
