How can PHP be used to update and display the account balance simultaneously?

To update and display the account balance simultaneously using PHP, you can retrieve the current balance from a database, update it with the desired amount, and then display the updated balance on the webpage.

// Retrieve current balance from database
$currentBalance = 1000;

// Update balance with desired amount
$amountToAdd = 500;
$newBalance = $currentBalance + $amountToAdd;

// Display the updated balance
echo "Current Balance: $" . $newBalance;
