How can PHP arrays be utilized to improve the code provided?

The code provided can be improved by utilizing PHP arrays to store the user input values and perform calculations on them more efficiently. By using arrays, we can dynamically store and access the values without the need for separate variables for each input. This will make the code more organized, scalable, and easier to maintain. 

<?php
// Initialize an empty array to store user input values
$userInputs = [];

// Loop through the input fields and store the values in the array
foreach ($_POST as $key => $value) {
    $userInputs[$key] = $value;
}

// Perform calculations using the values stored in the array
$total = array_sum($userInputs);

// Output the total
echo "The total is: " . $total;
?>
