How can PHP be used to perform calculations on user input values stored in a stack?

To perform calculations on user input values stored in a stack using PHP, we can first push the user input values onto the stack, then pop the values from the stack to perform the desired calculations. We can use PHP's array functions to simulate a stack data structure. 

<?php
// User input values
$input_values = [5, 10, 15];

// Initialize an empty stack
$stack = [];

// Push user input values onto the stack
foreach ($input_values as $value) {
    array_push($stack, $value);
}

// Perform calculations on values in the stack
$result = 0;
while (!empty($stack)) {
    $result += array_pop($stack);
}

// Output the result
echo "Result of calculations: " . $result;
?>
