我有一个ID数组：

var_dump($userPostsInternal);
  -> string(13) "128537,128545"

$args = array(
    \'post__in\' => array($userPostsInternal),
    \'post_type\' => \'post\',
    \'posts_per_page\' => -1,
);
$q = new WP_Query( $args );
foreach ( $q->posts as $post ) {
    $title = $post->title;
    echo $title;
}

我甚至试过：

foreach ( $q->posts as $post ) {
    $title = get_the_title();
    echo $title;

如果我爆炸了$userPostsInternal 我明白了array(2) { [0]=> string(6) "128537" [1]=> string(6) "128545" } 根本没有结果
