In the provided PHP code, what could be a more efficient way to handle individual account balances instead of updating all accounts with the same value?

The more efficient way to handle individual account balances instead of updating all accounts with the same value is to use an associative array where the keys represent the account numbers and the values represent the account balances. This way, you can directly access and update the balance of a specific account without affecting others. 

$accountBalances = [
    'account1' => 100,
    'account2' => 150,
    'account3' => 200
];

// Update balance of account2
$accountBalances['account2'] -= 50;

// Print updated balances
foreach ($accountBalances as $account => $balance) {
    echo "Account $account: $balance<br>";
}
