POST_RESULTS过滤器函数内存错误

我的posts_results 过滤器导致内存错误，我不知道为什么。以下是完整片段：

/*-----------------------------------------------------------------------------------*/
/* Filter posts after they are returned */
/*-----------------------------------------------------------------------------------*/
function my_posts_results_filter( $posts ) {

    $filtered_posts = array();

    //printr($posts);

    foreach ( $posts as $post ) {

        $post_type = get_post_type();
        if ( $post_type != \'post\' ) {
            $filtered_posts[] = $post;
            continue;
        }

        //Who can see this?
        $whosee = get_field(\'who_can_view\',$post->ID);
        $post_meta = get_post_meta($post->ID);

        //printr($post_meta);

        //What is this user\'s role?
        $user_id = get_current_user_id();
        $user_info = get_userdata($user_id);
        $user_role = $user_info->roles[0];
        if ( $user_role == \'subscriber\' || $user_role == \'author\' || $user_role == \'contributor\' || $user_role == \'editor\' ) $user_role = \'member\';

        if ( $whosee != "" ) {
            if ( $user_role == $whosee || $user_role == \'administrator\' ) {
                $filtered_posts[] = $post;
            }
        }

    }

    return $filtered_posts ;
}

if ( !is_admin() ) {
    add_filter( \'posts_results\', \'my_posts_results_filter\' );
}

任何想法都会很好。

谢谢Jay
