Answer 1

This might help, i haven't tested but you should and let me know.
public function getReport(){
$purchases = Purchase::all;
$result;
foreach($purchases as $p){
$itemsPurchased = $p->purchasedItems;
foreach($itemsPurchased as $pitem){
$pitem['item_details'] = $pitem->YOUR.FUNCTION.NAME.FOR.ITEM.DETAILS.
}
$p['purchased_items'] = $itemsPurchased;
$p['supplier_details'] = $p->supplierDetails;
$result = array($p);
}
return $result;
}

Answer 2

i made some changes and the below code works..
public function getAll(){
$array = Purchase::with('supplierDetails', 'purchasedItems')->get();
$purchases = json_decode($array,true);
$result = array();
foreach($purchases as $p){
$itemsPurchased = $p['purchased_items'];
foreach($itemsPurchased as $pitem){
$pitem['item_details'] = PurchasedItem::with('itemDetails', 'packageDetails')->where('purchase_id', '=', $pitem['purchase_id'])->get();
}
$p['supplier_details'] = $p['supplier_details'];
$p['purchased_items'] = $pitem['item_details'];
array_push($result, array($p));
}
return $result;
//[0] added to remove []sqauare bracket
}
