php asynchronous video processing issue? Ask God for guidance

Description of requirements:
Use the video solution of Baidu Cloud Platform. Its solution is to upload the mobile phone to its own server first, and then upload it from the own server to Baidu's server. Now it is hoped that the PHP background will complete the user's upload to its own server. server, returns to the user that the upload is successful, and then performs the upload to Baidu server. The problem encountered now is: the PHP backend waits for all executions to be completed before returning to the client. It makes you wait for a long time every time.

I wonder if any of the masters can give me some guidance? As a front-end developer, I am a beginner in PHP and have encountered many problems. Thank you all.

If your PHP service uses PHP-FPM, you can open a process pool specifically for processing video upload operations. The script uses fastcgi_finish_request to quickly respond to the user's request and perform time-consuming upload processing.

<code><?php
echo '手机端视频先上传至自有服务器';
sleep(10);
echo '上传成功';
fastcgi_finish_request(); //响应用户,结束请求
echo '程序继续操作,从自有服务器上传至百度服务器';
sleep(10);</code>

PHP-FPM will not be blocked during the file upload process, because Nginx will hand it over to PHP-FPM all at once after receiving the uploaded content.
The operation of "uploading from own server to Baidu server" will block and occupy a PHP -FPM worker process.
At this time, you can consider establishing an upload process pool to handle this operation to avoid blocking other scripts in the system.

<code>nginx.conf: upload.php脚本的处理都交给监听9001的PHP-FPM进程池处理
location = /upload.php {
    include fastcgi_params;
    fastcgi_pass 127.0.0.1:9001;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

php-fpm: 正常的脚本由静态www池处理,网络阻塞脚本由动态upload池处理
[www]
listen = 127.0.0.1:9000
pm = static
pm.max_children = 4
[upload]
listen = 127.0.0.1:9001
pm = dynamic
pm.max_children = 8
pm.start_servers = 4
pm.min_spare_servers = 4
pm.max_spare_servers = 4</code>

You can use a queue. After the user completes the upload, he directly puts a task into the queue and then returns to complete the upload. The system then executes a scheduled task to run the queue. There are several forms of queue application, you can search and see
