A for loop putting 2 posts in an li - with WordPress

gistfile1.php

<?php

// Define the arguements as you would for a WP_Query
$args = "whatever"; 
// Run get_posts instead of WP_Query, does a similar thing but now $slide_posts 
// will contain the query results in an array...
$slide_posts = get_posts($args);

// FOR LOOP! 
// 3 arguments (counter), (the test to see how many loops to run - for as long as i < the count of the array) (increment counter)
for ( i=0; i<count($slide_posts); i++ ): ?>
	
	<li>
		<?php 
		// return the first post - look up the $post object and see how it returns
		// access things like title with $slide_posts[i]->post_title;
		echo $slide_posts[i]; 

		// increment the counter (i)
		i++;

		// return the second post - look up the $post object and see how it returns
		echo $slide_posts[i];
		?>
	</li>

<?php endfor; ?>
