I want to check for example Brand “Apple” Exist as a term in Brands Attribute, then setup the brand apple to this product as taxonomy type.

$product_id = 214246; 
$product = wc_get_product($product_id);

check if the product exist

   if ($product) {  
   $attributes = $product->get_attributes();

if (!empty($attributes)) {
    // Loop through each attribute
    foreach ($attributes as $attribute) {
        // Get the attribute label
        $attribute_label = wc_attribute_label($attribute->get_name());

        // Get the attribute value
        $attribute_value = '';

        // Check if the attribute is a taxonomy type
        if ($attribute->is_taxonomy()) {
            $attribute_value = implode(', ', wc_get_product_terms($product->get_id(), $attribute->get_name(), array('fields' => 'names')));
        } 

        // Display the attribute label and value
        echo '<p><strong>' . $attribute_label . ':</strong> ' . $attribute_value . '</p>';
    }
} else {
    
    // I want to add if the brands Apple exist if not then add apple as a brand then set this brand to this product.

}

}

Thank You
