Examples
#1 Get the post ID
Usually the post ID inside the loop can be obtained through $post->ID, but in some cases it may be useful to get it like this:
$post_id = get_the_ID(); // $post_id will contain the ID of the current post in the loop
#2 Display the meta field of the post using the get_the_ID() function:
$post_id = get_the_ID(); echo get_post_meta( $post_id, 'meta_key', 1); // or can be so: echo get_post_meta( get_the_ID(), 'meta_key', 1);
