$post->post_parent ??? etc

Hey guys,

Sorry, this will sound dumb but what are the significance of these values:

$post->post_status
$post->comment_status
$post->ping_status
$post->post_pingback
$post->post_category
$post->post_content
$post->post_title
$post->post_excerpt
$post->page_template
$post->post_parent
$post->menu_order

Pretty new to PHP really, and searching for ‘->’ is a nightmare as you can probably appreciate.

I’ll pulled the values from this page BTW: http://codex.wordpress.org/Template_Tags/get_the_title

Thanks,
L
