Simplify your nested Laravel collection with pluck function or using crossJoin and eachSpread

NestedCollection.php

<?php

$customers = collect([]); // some nested Laravel collection

// Instead of manually creating this monstrous nested loop...
$customers->each(function ($customer) {
    $customer->orders->each(function ($order) {
        $order->payments->each(function ($payment) {
            //doWork($payment);
        });
    });
});

// we can use pluck with dots and stars to fetch deeply nested layers
$customers->pluck("orders.*.payments")->flatten()->each(function ($payment){
    //doWork($payment);
});

//------- ------- ------- ------- ------- ------- //
// or this nested loop
$customers->each(function ($customer) use ($teams, $dates) {
    $teams->each(function ($team) use ($customer, $dates) {
        $dates->each(function ($date) use ($customer, $team) {
            doWork($customer, $team, $date);
        });
    });
});

// to this
$customers->crossJoin($teams, $dates)->eachSpread(function ($customer, $team, $date) {
    doWork($customer, $team, $date);
});
