What are some best practices for iterating through arrays and processing checkbox values in PHP?

When iterating through arrays and processing checkbox values in PHP, it is important to use a loop to iterate through the array of checkbox values and handle each value accordingly. This can be done by checking if the checkbox is checked (i.e., if the value is present in the array) and performing the necessary processing based on the checkbox value. 

// Assuming the checkbox values are submitted as an array
$checkbox_values = $_POST['checkbox_values'];

foreach ($checkbox_values as $value) {
    // Check if the checkbox is checked
    if (isset($value)) {
        // Process the checked checkbox value
        // For example, you can perform some action or store the value in a database
        echo "Checkbox with value $value is checked.";
    } else {
        // Process the unchecked checkbox value
        // For example, you can set a default value or ignore it
        echo "Checkbox with value $value is unchecked.";
    }
}
