Get data from apply_filters('prefix_xml_feeds_productname_variant') function in WooCommerce

I'm totally new to WordPress and WooCommerce, so apologies for the poor explanation.

I have this code:

$text = apply_filters( 'prefix_xml_feeds_productname_variant', $text, $product_item->ID, $vars->ID );

And need to display $vars->ID in my function:

So I got:

function custom_product_name() {
    global $product;
    
    $product_name = $product->get_name();
    $sku = $product->get_sku();
    
    $text = 'Example.com ' . $sku . ' ' . $product_name . ' ' . $vars->ID;         
    return $text; 
}
add_filter( 'prefix_xml_feeds_productname_variant', 'custom_product_name' );

How can I access $vars variable value in my callback function?

As you can see apply_filters( 'prefix_xml_feeds_productname_variant', $text, $product_item->ID, $vars->ID ); contains 3 parameters

So you could use it like

function custom_product_name( $text, $product_id, $vars_id ) {
    // Get product object   
    $product = wc_get_product( $product_id );

    // Is a product
    if ( is_a( $product, 'WC_Product' ) ) {
    
        // Get product name
        $product_name = $product->get_name();

        // Get product sku
        $sku = $product->get_sku();
    
        // Output
        $text = 'Example.com ' . $sku . ' ' . $product_name . ' ' . $vars_id; 
    }
    
    return $text; 
}
add_filter( 'prefix_xml_feeds_productname_variant', 'custom_product_name', 10, 3 );

Using filter hooks

Filter hooks are called throughout are code using apply_filter( 'filter_name', $variable );. To manipulate the passed variable, you can do something like the following:

add_filter( 'filter_name', 'your_function_name' );

function your_function_name( $variable ) {
    // Your code
    return $variable;
}

With filters, you must return a value.
