loop php

<?php
/**
 * The loop that displays posts.
 *
 * The loop displays the posts and the post content.  See
 * http://codex.wordpress.org/The_Loop to understand it and
 * http://codex.wordpress.org/Template_Tags to understand
 * the tags used in it.
 *
 * This can be overridden in child themes with loop.php or
 * loop-template.php, where 'template' is the loop context
 * requested by a template. For example, loop-index.php would
 * be used if it exists and we ask for the loop with:
 * <code>get_template_part( 'loop', 'index' );</code>
 *
 * @package WordPress
 * @subpackage Revolution
 * @since Revolution 1.0
