有一个功能,不知道如何下手,求各位大大指教!
做的是一个提醒功能:
比如现在数据库中有一条记录,是需要在指定的某个时间发送邮件的。怎么做?
1、提醒方式:
·邮件,先请教邮件的。
·短信
2、提醒时间:
·到点提醒(即某年某月某日某时某分某秒)
·每天提醒(即每天的某时某分某秒)
·每周提醒(即每周的周几的某时某分某秒)
------解决方案--------------------
1.定时功能 达到条件
2.读取数据库记录
3.send mail 短信的话直接到时间post/get到短信接口
有什么不知道如何下手呢?三条一条一条处理。你需要那么详细的提醒功能用linux比较好处理.
------解决方案--------------------
你猜对了
------解决方案--------------------
PHP自身没有定时执行的可能,除非在任务管理器中定时启动这个脚本,或者有人访问你的网站时触发
------解决方案--------------------
我不访问你的网站,看你提醒谁
------解决方案--------------------
你是想做网站的邮件订阅吗?那最起码有个email地址吧,不然你把邮件发给谁啊。
------解决方案--------------------
提示一下 触发器 或者在程序中写 到达某一个时间的时候访问一次数据库
------解决方案--------------------
在linux下定时访问你写的接口
------解决方案--------------------
做脚本然后自动运行啊!

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP 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.
