Are there any specific PHP functions or methods that can simplify the handling of checkbox arrays in forms?

When dealing with checkbox arrays in forms, it can be cumbersome to handle the data that is submitted. One way to simplify this process is by using the `array_filter` function in PHP. This function can be used to remove any empty or unchecked values from the array, making it easier to work with the data that is actually selected by the user. 

// Assuming the form field name is 'checkboxes[]'
$checkboxes = $_POST['checkboxes'] ?? []; // Get the checkbox array from the form data

// Filter out any unchecked checkboxes
$selectedCheckboxes = array_filter($checkboxes);

// Now $selectedCheckboxes contains only the values of the checked checkboxes
