使用 PHP，我可以将 foreach 语句放入瞬态中吗

我正在用可湿性粉剂和PHP工作，并试图减少我的加载时间的函数，抓取一堆数据.我认为瞬变语句可以工作，并且(如下面所示)我在瞬变语句下加载了课程查询，但是它不能在Foreach语句上工作，或者更确切地说，我不知道如何正确地设置它才能工作.

让一切变慢的主要代码是Foreach语句，该语句获取每个主题的Vimeo视频id，通过Vimeo_api()函数运行它，然后获取视频的持续时间，然后将其附加到数组中的主题id.

从技术上讲，我不必使用Get_Vimeo_Duration_All_Coursees()函数(which calls all the courses/lessons/topics)，而是在加载时从每个主题获取Vimeo ID，因为这是我一开始使用的方法，它确实有效，但不幸的是它增加了我的页面加载时间.我的 idea 是，如果我可以加载数组中的所有持续时间，并将每个持续时间附加到主题ID，那么我就不必在每次想要获得视频持续时间时调用Vimeo_API()函数.我可以做的更多，只需每天更新$Vimeo变量一次，然后在$Vimeo变量中搜索主题ID以获得Vimeo持续时间.

So I guess I'm wondering if I'm heading in the right direction or if you know of a better way to go about it?个

Is there a way that I can store the $vimeo variable with all the values inside of it so that the vimeo_api() function doesn't have to run each time?个

任何帮助都是令人惊叹的！谢谢

function get_vimeo_duration_all_courses($vimeo)
{
    $courses = get_transient('all_courses'); 
    if (false === $courses) {

        $courses = new WP_Query(array(
            'posts_per_page' => -1,
            'post_type'  => 'sfwd-courses',
            'no_found_rows' => true,
            'cache_results' => true,
            'ignore_sticky_posts'  => true,
            'fields' => 'ids',
        )); //Grabs all the courses

        set_transient('all_courses', $courses, (24 * HOUR_IN_SECONDS));
    }

    $vimeo = get_transient('all_vimeo_durations');
    if (false === $vimeo) {
        $vimeo = array();

        foreach ($courses->posts as $course_id) {
            $lessons = learndash_course_get_lessons($course_id); //Gets all the lessons under the course
            
            foreach ($lessons as $lesson) {
                $topics = learndash_course_get_topics($course_id, $lesson->ID); //Gets all the topics under the lesson
                
                foreach ($topics as $topic) {
                    $vimeoVideo = get_field('lesson_video', $topic->ID); 
                    
                    if (!empty($vimeoVideo)) { //Looks at each topic and determines whether it has a vimeo video or not
                        $vimeoDuration = vimeo_api($vimeoVideo); //If true, it runs the vimeo ID through the vimeo_api() function (THIS IS WHERE IT BECOMES SLOW)
                        $vimeo[$topic->ID] = $vimeoDuration;
                    }
                }

            }

        }

        set_transient('all_vimeo_durations', $vimeo, (24 * HOUR_IN_SECONDS));
    }

   return $vimeo;
}


function show_vimeo_duration($topicID) {
    return $vimeo[$topicID]; //Returns the value of the vimeo_api() function that matches the topicID
}

下面是我获取Vimeo API并返回视频时长的地方

function vimeo_api($id)
{
    try {
        $authorization = 'CODELEFTOUTONPURPOSE';
        $ch = curl_init();

        curl_setopt_array($ch, array(
            CURLOPT_URL => "https://api.vimeo.com/videos/$id?fields=duration",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_ENCODING => "",
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 30,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => "GET",
            CURLOPT_HTTPHEADER => array(
                "authorization: Bearer {$authorization}",
                "cache-control: no-cache",
            ),
        ));

        $res = curl_exec($ch);
        $obj = json_decode($res, true);
        return $obj['duration'];//Returns the duration of the video
    } catch (Exception $e) {
        return "0";
    }
}
