running a loop

Try using an array. Example:

<?php $postID = array(); ?>
<!-- the loop -->
<?php while ( have_posts() ) : the_post(); ?>

<!-- inside the loop -->
<?php $postID[] = get_the_ID(); ?>

<?php endwhile; ?>
<?php
// print the ids
if ( !empty( $postID ) ) {
	foreach ( $postID as $id ) {
		echo 'post id = ' . $id;
	}
}
?>
