把要做的计算业务先推入mq,就是任务队列,这个可以用redis去做。
Linux跑脚本,一直消费队列。

用redis实现一个队列,每次把相关信息放到队列中,然后返回给用户code,队列里的数据用脚本去跑

Gearman

你需要的应该是这个

异步操作

php 计算问题

把计算当做一个任务,放到队列中,有一个脚本在跑,从队列里获取任务,然后在后台处理.
这也就是需要所谓的消息队列,可以看下 rabbitmq,gearman 等消息队列.
我这里写了一篇 php rabbitmq 的使用方法,可以看下.

上面各位大神提到将计算任务放到消息对队中, 确是一种不错的方案。 但是需要搭建队列服务。

如果计算量不是特别巨大的, 是不是可以fork一个进程来解决更简单呢。

参考一下YII框架的Request对象的onEndRequest方法,该方法是一个可以实现异步调用。

比较同意 @zyxcba 的回答,如果量不大的话是可以先把数据 flush 出去,然后再 fork 一个进程来处理具体的计算任务的,不过 pcntl 扩展只能在 Linux 上面使用。

如果计算的数据不需要返回给用户,可以先行返回继续执行代码的。php-fpm可以使用这个fastcgi_finish_request,echo 返回值,fastcgi_finish_request(),后面继续执行。。。。或者就是使用队列了

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

Explain how to use sessions for user authentication.Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AM

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
