如何在wordpress中从这个对象数组中检索我的值

$args = array(
    'post_type' => 'post',
    'posts_per_page' => 10
);
$posts = get_posts($args);

foreach ($posts as $post) {
    $title = get_the_title($post->ID);
    $permalink = get_permalink($post->ID);
    // 打印标题和链接
    echo "标题：$title<br>";
    echo "链接：$permalink<br>";
}

foreach ($posts as $post) {
    if (has_category('技术', $post->ID)) {
        $title = get_the_title($post->ID);
        $permalink = get_permalink($post->ID);
        // 打印标题和链接
        echo "标题：$title<br>";
        echo "链接：$permalink<br>";
    }
}
