How to get total amount from foreach lop in Laravel Controller - laravel

Question

I want to get total amount from foreach lop data in the controller, for example, code bellow.
$set = settings::findOrFail(1);
$api = new \Binance\API("$set->api_key","$set->scrt_key");
$api->useServerTime();
$forusdvaluetotal = coins::whereuser_id(Auth::user()->id)->get();
foreach($forusdvaluetotal as $coins){
$getsymbol = $coins->symbol.'USDT';
$getprice = $api->price("$getsymbol");
$valueinusd = $coins->balance*$getprice;
$total = $valueinusd;
}
$gettotal = $total->sum();
like "coins A" price is $50 per coin and balance 2, "coins B" price is $50 per coin and balance 5, "coins C" price is $50 per coin and balance 1. So I want to get total amount in USD by balance like ('coins A' $502 = $100 + 'coins B' $505 = $250 + 'coins A' $50*1 = $50) = $400
Please help me how to solve that in laravel controller.

Answer 1

Try this:
$total = 0;
foreach($forusdvaluetotal as $coins){
$getprice = $coins['market_price'];
$valueinusd = $coins['balance']*$getprice;
$total += $valueinusd;
}
return $total;

Answer 2

One elegant option would be to make use of Laravel's support collection method reduce().
The reduce method reduces the collection to a single value, passing
the result of each iteration into the subsequent iteration:
The value for $carry on the first iteration is null; however, you
may specify its initial value by passing a second argument to
reduce:
$collection = coins::whereuser_id(Auth::user()->id)->get();
$total = $collection->reduce(function ($carry, $item) {
return $carry + (floatval($item->balance) * floatval($item->market_price));
}, 0);
Addendum
Alternatively, you may make use of Laravel's support collection method sum().
The sum method returns the sum of all items in the collection:
In addition, you may pass your own closure to determine which values
of the collection to sum:
$collection = coins::whereuser_id(Auth::user()->id)->get();
$total = $collection->sum(function ($item) {
return (floatval($item->balance) * floatval($item->market_price));
});
Edit:
In response to your new question changes, you could solve it this way.
$set = settings::findOrFail(1);
$api = new \Binance\API("$set->api_key","$set->scrt_key");
$api->useServerTime();
$query = coins::whereuser_id(Auth::user()->id);
// Get symbols.
$symbols = (clone $query)->distinct('symbol')->pluck('symbol')->flip()->toArray();
// Fetch prices.
array_walk($symbols, function (&$value, $key) use ($api) {
$value = $api->price("{$key}USDT");
});
// Get total sum.
$total = $query->get()->reduce(function ($carry, $item) use ($symbols) {
return $carry + (floatval($item->balance) * floatval($symbols[$item->symbol]));
}, 0);
