我有一个对象$post_object。我想从中获取ID。我将如何实现它？我将它视为数组但我的页面卡住了，我无法看到它的值。这是我的目标。
WP_Post Object
(
[ID] => 457
[post_author] => 1
[post_date] => 2015-12-14 06:40:12
[post_date_gmt] => 2015-12-14 06:40:12
[post_content] =>
[post_title] => The Biggie
[post_excerpt] =>
[post_status] => publish
[comment_status] => closed
[ping_status] => closed
[post_password] =>
[post_name] => the-biggie
[to_ping] =>
