Select objects from get_posts()

Question

How can I select the first/last object from the list returned by get_posts()?

How can I select the preceding/following object relative to an arbitrary object in the object list returned by get_posts?

How can I extract a sublist from the list returned by get_posts()?

This sounds like more of PHP question than a WordPress one - get_posts() just returns an array of objects; interact with them like you would any other numerical array:

$posts = get_posts();

$first_post = $posts[0];
$last_post = array_slice( $posts, -1, 1 );

$everything_but_first_last = array_slice( $posts, 1, -1 );

Check out the complete list of array functions.

	Thanks for the list. For some reason I can only reference by index the first eight objects, even though `print_r($objects);` prints them all out (all 123 objects), as does a `foreach` loop. I get `Undefined offset: 8` for index 8 and other higher that I've tried. Any ideas why? – seron Aug 6 '12 at 15:56
	My code was bad. I can now reference any index. – seron Aug 6 '12 at 18:52
	The list of PHP array functions was very useful. I found answers to my questions using that and some examples I found on the web. In particular, I used array_keys combined with array_search to get the preceding/following object inspired by this Stack Overflow post link – seron Aug 18 '12 at 6:42
