php站内通知问题 如何实现呢
只需要站内通知
管理可以后台发送通知(群发和对指定会员发送通知) 用户只接受查看通知 无发送权限
目前有一张 my_messages表
结构如下
给指定会员发送通知 肯定是要 在my_messages插入一条数据了
全站会员群发通知要怎么设计表 和 实现呢
回复讨论(解决方案)
每个会员插入一条记录?
应该是这样
表设计:发送者uid,接收者uid,内容。
群发的时候,获取所有接收者uid。
我觉得你得用两张表比较好,一个存储用户消息(usermsg),有userid,msgid,status
另外一张表(msg)存储消息内容,id,content,inserttime等,
如果要给群组发,先插入 msg表,然后将id插入到usermsg表中,这样感觉比较好
如果是我的话,我的表结构会是:
id message userlist
id 消息正文 所有用户的id拼凑出一个array,然后串行化变成string类型的数据存入这一列
当某个人已读取的时候就取得userlist的内容,然后反串内容变成array,把那个用户的id删掉再串行化存入userlist列.

sibang
这样也省不了多少吧 比如群发十万条;那你那userlist 不就变成很大一串。 text都不够放。
然后你要查某个用户是否有新信息也不好查
我也遇到这样的问题,
2个表
一个表存储通知信息:id、title、content、ctime、author、state
另一个表存储用户是否阅读的信息:
id、sid(对应通知表id)、uid(用户id)、view(是否阅读)、hide(是否清空)、ctime
你认为呢?

In 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 and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

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.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.
