Basket Serialisation

[kb6673]

We're running some external validation on basket contents.
(Using woocommerce_check_cart_items to check items against an ERP system)

In short, it reads the serialised basket contents from wp_options.option_value
Most of the baskets unserialize correctly, eg

{s:10:"product_id";i:8865; (Snippet)

However some baskets store the product_id as a string, however all product_ids are integers

{s:10:"product_id";s:4:"8525"(Snippet)

We're wondering whether this is a Woo, WP or PHP bug within the basket serialization.

There is no type casting on product_id. Will make them consistent in 2.4.
