select column from an array based on id - laravel

Question

I want to filter through this array $bank_totals and select a value of amount only.
$bank_totals = $bank_totals->bank_balances();
"id" => 1
"bank" => "KCB"
"amount" => 7622.0
]
1 => array:3 [
"id" => 2
"bank" => "I & M Bank"
"amount" => 25000.0
am getting the id from user input $data['id']; I want when the $data['id'] = 2 example the value shown is 25000
$data = request()->all();
$bank_totals = $bank_totals->bank_balances();
(to appear here)
here is my bank_balances method
class TransactionsRepository
{
public function bank_balances(){
$banks_data = Bank::all();
$banks_totals = [];
foreach ($banks_data as $bank){
$totals = (BankingTransactions::where('bank_id', $bank->id)->sum('amount')) -
((PettyCash::where('bank_id', $bank->id)->sum('amount')) + ((PayDoctor::where('bank_id', $bank->id)
->sum('total_paid'))));
array_push($banks_totals,
[
'id'=>$bank->id,
'bank'=>$bank->name,
'amount'=>$totals,
]);
}
return $banks_totals;
}
}

Replace your bank_balances method with this:
public function bank_balances($id = null) {
$banks_data = Bank::all();
$banks_totals = [];
if (is_null($id)) {
foreach ($banks_data as $bank) {
$totals = (BankingTransactions::where('bank_id', $bank->id)->sum('amount')) -
((PettyCash::where('bank_id', $bank->id)->sum('amount')) + ((PayDoctor::where('bank_id', $bank->id)
->sum('total_paid'))));
array_push(
$banks_totals,
[
'id' => $bank->id,
'bank' => $bank->name,
'amount' => $totals,
]
);
}
return $banks_totals;
} else {
return (BankingTransactions::where('bank_id', $id)->sum('amount')) -
((PettyCash::where('bank_id', $id)->sum('amount')) + ((PayDoctor::where('bank_id', $id)
->sum('total_paid'))));
}
}
And use it like this:
$bank_totals = $bank_totals->bank_balances($data['id']);
