What considerations should PHP developers keep in mind when designing forms with multiple checkbox options that require specific sorting criteria?

When designing forms with multiple checkbox options that require specific sorting criteria, PHP developers should consider implementing an array to store the checkbox values and then sorting the array based on the desired criteria. This can be achieved by using PHP functions like array_push() to add checkbox values to the array and array_multisort() to sort the array based on specific criteria. 

// Initialize an empty array to store checkbox values
$checkbox_values = array();

// Add checkbox values to the array
if(isset($_POST['checkbox_name'])) {
    foreach($_POST['checkbox_name'] as $value) {
        array_push($checkbox_values, $value);
    }
}

// Sort the array based on specific criteria
array_multisort($checkbox_values, SORT_ASC);

// Display the sorted checkbox values
foreach($checkbox_values as $value) {
    echo $value . "<br>";
}
