What are some best practices for iterating through checkbox values in PHP form submissions to process multiple selections efficiently?

When processing multiple checkbox selections in a PHP form submission, it is best to iterate through the checkbox values efficiently to handle each selection appropriately. One common approach is to use a foreach loop to loop through the array of checkbox values and perform the necessary actions based on the selected values. 

// Assuming 'checkbox' is the name attribute of the checkboxes in the form
if(isset($_POST['checkbox']) && is_array($_POST['checkbox'])) {
    foreach($_POST['checkbox'] as $value) {
        // Process each selected checkbox value here
        echo "Selected value: " . $value . "<br>";
    }
}
