获取数组中对象的键值？

Question

I am someone who has been trying out webdesign for around 2 months now and I have a question. So I have the following array with object:

array(1) {
  [0]=>
  object(WP_Post)#416 (24) {
  ["ID"]=>
  int(36)
  ["post_title"]=>
  string(7) "Bakuman"
}

I am trying to get the value of "ID", but am not sure how to go about referencing it.
I have tried [0]["ID"], but doesn't work.

Also: Is it possible to get the ID without mentioning the #416 number?

Tried searching for answer, but keep coming up with results that have large amounts of OOP with so much info I can't filter through to what I need. Can anyone hlpe me out?

Answer 1

PHP uses -> for object properties.

So in your case

echo $array[0]->ID;

should output 36

where [0] is the first element of $array which contains the WP_Post object and ID is the property containing the value you're looking for
