I am using WordPress and I have the following Object Array from my post table and I want to extract guid element of this array. How do I extract this?

Answer 1

Just use get_the_guid( $post->ID ); .

See: https://developer.wordpress.org/reference/functions/get_the_guid/

Answer 2

获取密钥，然后获取其中的对象

                  <p>echo $array_name[array_keys($array_name)[0]]->{guid};</p>
