// Example 1: Validating a boolean value from a form submission
$submitted_value = $_POST['is_active']; // Value can be '1' or '0'
$validated_value = wp_validate_boolean( $submitted_value );
if ( $validated_value === false ) {

// Example 2: Using wp_validate_boolean to sanitize a custom field value
$custom_field_value = get_post_meta( $post_id, 'is_featured', true ); // Value can be '1' or '0'
$validated_value = wp_validate_boolean( $custom_field_value );
if ( $validated_value === false ) {
