PHP extract value form a variable

Question

I'm working on WordPress plugin, It have a variable called $item, which holds some data of a post.

I use var_dump function to display it's data,

var_dump($item);

but i couldn't able to get a value of a single item.

I just need to get item_id and item_order

Can someone help me to get this values and assign to a another variable. Thank You

Here is the dump

object(LP_Lesson)#11313 (5) { 
    ["id"]=> int(6915) 
    ["post"]=> object(WP_Post)#11357 (29) { 
    ["ID"]=> int(6915) ["post_author"]=> string(1) "1" 
    ["post_date"]=> string(19) "2015-06-05 04:29:56" ["post_date_gmt"]=> string(19) "2015-06-05 04:29:56" ["post_content"]=> string(5971) "" ["post_title"]=> string(20) "Add and manage users" ["post_excerpt"]=> string(1) " " ["post_status"]=> string(7) "publish"

        ["section_id"]=> string(1) "1" 
        ["item_id"]=> string(4) "6915" 
        ["item_order"]=> string(1) "3" 
        ["item_type"]=> string(9) "lp_lesson" } 
        ["content"]=> string(0) "" ["lesson_type"]=> NULL ["_item":protected]=> object(WP_Post)#11357 (29) { ["ID"]=> int(6915) ["post_author"]=> string(1) "1" ["post_date"]=> string(19) "2015-06-05 04:29:56" ["post_date_gmt"]=> string(19) "2015-06-05 04:29:56" ["post_content"]=> string(5971) "

since it is an object, just echo

$item->id & $item->post->item_order

Did you try:

$item_id = $item->item_id

and

$item->post->item_order; //as instructed by @AliAwwad

? By the way, I see that the id, is the same with item_id, so for that for sure you can do:

$item_id = $item->id;

Is there some scope indication that I'm failing to see?

It's an object, so accessing it as an array is not going to work.

Thank you for pointing it out! I've been going front and back to python the last couple of weeks and my syntax gets mixed up!
