What are some best practices for handling and organizing checkbox values in PHP to ensure efficient processing and sorting?

When handling and organizing checkbox values in PHP, it is essential to properly structure the data to ensure efficient processing and sorting. One way to achieve this is by using arrays to store the checkbox values as keys with boolean values indicating whether they are checked or not. This allows for easy retrieval and manipulation of the checkbox values. 

// Sample code for handling checkbox values in PHP

// Initialize an empty array to store checkbox values
$checkboxValues = [];

// Loop through the checkbox inputs
foreach ($_POST['checkbox'] as $checkbox) {
    // Set the checkbox value as key in the array with a boolean value indicating if it's checked
    $checkboxValues[$checkbox] = true;
}

// Sort the checkbox values alphabetically
ksort($checkboxValues);

// Output the sorted checkbox values
foreach ($checkboxValues as $value => $checked) {
    echo $value . " is checked: " . ($checked ? 'true' : 'false') . "<br>";
}
