How can PHP arrays be used to simplify the process of summing values from active checkboxes?

When dealing with multiple checkboxes, PHP arrays can simplify the process of summing values by dynamically storing the selected checkbox values in an array. This allows for easy iteration through the array to calculate the total sum of the selected values. 

<?php
// Assuming checkboxes are named 'checkbox[]' in the HTML form

if(isset($_POST['checkbox'])) {
    $selectedValues = $_POST['checkbox'];
    $totalSum = array_sum($selectedValues);
    
    echo "Total sum of selected checkboxes: " . $totalSum;
}
?>
