How to get the session ID of a product?

Question

WordPress

On the "Shopping cart" page, I get the session of the cart items with the request:
$cart = WC()->session->get( 'cart', null );
At the output, I get a list of data for all products in the basket:
array(2) { ["c6ea20f4f2db4fdc4578906a64721348"]=> array(13) {
["is_deposit"]=> bool(true)
["payment_plan"]=> int(1)
[ "product_id"]=> int(10633)
["variation_id"]=> int(0)
["variation"]=> array(0) { }
["quantity"]=> int(1)
["deposit_amount"] => string(1) "0"
["full_amount"]=> int(700)
["line_total"]=> int(0)
["line_tax"]=>
["total"]=> array(1) {
[1]=> float(0)
} ["total"]=> array(1) { [1]=> float(0)
["subtotal"]=> array(1) { [1]=> float(0) } } }
["4706d250811ba7663a8f6f7849a4bfbd"]=> array(13) {
["is_deposit"]=> bool(true)
["payment_plan "]=> int(2)
["product_id"]=> int(9540)
["variation_id"]=> int(0)
["variation"]=> array(0) { }
["quantity"]=> int(1)
["deposit_amount"]=> string(1) "0"
["full_amount"]=> int(500)
["line_total"]=> int(0)
["line_tax"]=> float(0 )
["line_subtotal"]=> int(0)
["line_subtotal_tax"]=> float(0)
["line_tax_data"]=>
}
["subtotal"]=> array(1) { [1]=> float(0) } } }
Question:
How do I get the key (example: ["c6ea20f4f2db4fdc4578906a64721348"]=> array(13) ) of the session specifically for one or another product,
that is, I need to display only its data for each product.
For what?
I need to get one of the product related values ​​and change it.

Answer 1

array_keys()
And you might want to read some more about sessions. Judging by phrases like "sessions related to the product" it seems that you do not quite understand what it is, how it works and why.
