How to get an array of post data from wp_query result?

Question

When run a query with WP_Query method, I got an object. I understand that I can then do the loop to display stuffs. But, my goal is not to display anything, instead, I want to get some post data by doing something like "foreach...". How can I get an array of post data that I can loop through and get data?

You should read the function reference for WP_Query on the WordPress codex. There you have a lot of examples to look at. If you don't want to loop over the resultset using a while, you could get all posts returned by the query with the WP_Query class method get_posts().

For example

$query = new WP_Query(array('post_type' => 'page'));
$posts = $query->get_posts();

foreach($posts as $post) {
    // Do your stuff, e.g.
    // echo $post->post_name;
}
