What are best practices for displaying and saving checkbox values in PHP?

When working with checkboxes in PHP, it is important to properly handle their values when displaying and saving them. To display checkbox values, you can use the isset() function to check if the checkbox is checked and then display the appropriate value. When saving checkbox values, you can use the ternary operator to set the value to either true or false based on whether the checkbox is checked or not. 

// Displaying checkbox values
$checkboxValue = isset($_POST['checkbox']) ? 'checked' : '';

echo '<input type="checkbox" name="checkbox" value="1" ' . $checkboxValue . '>';

// Saving checkbox values
$checkbox = isset($_POST['checkbox']) ? true : false;

// You can then save the $checkbox value to a database or use it in further processing
