php执行群发邮件、消息等任务，怎么样在web端输出实时的结果？
两种思路，一种是把多条任务分拆成单条任务，然后前端每次发一个请求，不过这种不是很靠谱，如果浏览器崩溃或者网络断掉就挂掉了。比较适合对任务的完整性要求不高，而且需要快速实现的场合。
另外一种思路就是后端做一个脚本异步接收任务队列，然后把任务完成的情况写入到一个缓存中，浏览器端通过每隔一段时间去取这个缓存结果来获知后端脚本的运行情况。
php + redis 任务队列 或 gearman
可以使用flush函数来查看实时结果，或者打开ob缓存，然后使用ob_flush和flush函数来将程序缓存强制刷新到浏览器查看结果。希望对你有用!
一种方法是使用设置较长的执行时间并使用ob系列函数即时输出内容, 一种是Html5 Websocket + php socket
最简单是每输出一次结果都进行flush，如果是nginx要把buffer设置得尽可能小
做成队列，慢慢执行，执行完成改状态，开一个页面查询最新执行完成的任务
web端=>任务队列
根据经验，这种方式比较好

有何不妥嗎？
可以參照 wordpress 在線安裝更新時採用的解決方案
发送一条，浏览器刷新一次，继续执行下一条。url中记录执行到哪一步了，比如规定发送5封邮件为一步，xxx/send.php?step=1 执行完成后，页面刷新，跳转到xxx/send.php?step=2 ，依次类推。刚才踩我答案 ，基本可以判断为经验不足的菜鸟，连这种方案都没见过。
How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AMPHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AMIn PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
PHP vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AMPHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AMKey players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.
Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AMIn PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
PHP: An Introduction to the Server-Side Scripting LanguageApr 16, 2025 am 12:18 AMPHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.
PHP and the Web: Exploring its Long-Term ImpactApr 16, 2025 am 12:17 AMPHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.
Why Use PHP? Advantages and Benefits ExplainedApr 16, 2025 am 12:16 AMThe core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
