php limits a certain number of queries every day, how to achieve it?
Correct answer upstairs.
If it is limiting the query volume for a single user, the cumbersome method is to write it into the database, increment it in sequence, and clear it at 12 o'clock in the evening. A scheduled task may be used to clear it.
A good way is to use user ID+identification
as key
and write it into redis.
If it is not limited based on a single user, but based on all query volume, in addition to the above two methods, there is another way to write into a text file. When used, read
, compare
, +1
,write
In fact, based on the above, the only required actions are get value
, compare
, +1
, write
, but the medium is different, it depends on the needs.
By the way, it can also be used with scheduled tasks if necessary.
Simply put, it means one query and one entry. There is no difference in principle from human restricted query.
Basic idea: Query once and increment the database once.
When the query volume is large, the performance will naturally be poor.
Then use Redis or the like, and cache it into the memory first for each increment to improve efficiency. Updated as a whole every once in a while/a certain amount

PEAR is a PHP framework for reusable components, enhancing development with package management, coding standards, and community support.

PHP is a versatile scripting language used mainly for web development, creating dynamic pages, and can also be utilized for command-line scripting, desktop apps, and API development.

The article discusses PHP's evolution from "Personal Home Page Tools" in 1995 to "PHP: Hypertext Preprocessor" in 1998, reflecting its expanded use beyond personal websites.

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.

To destroy a PHP session, you need to start the session first, then clear the data and destroy the session file. 1. Use session_start() to start the session. 2. Use session_unset() to clear the session data. 3. Finally, use session_destroy() to destroy the session file to ensure data security and resource release.

How to change the default session saving path of PHP? It can be achieved through the following steps: use session_save_path('/var/www/sessions');session_start(); in PHP scripts to set the session saving path. Set session.save_path="/var/www/sessions" in the php.ini file to change the session saving path globally. Use Memcached or Redis to store session data, such as ini_set('session.save_handler','memcached'); ini_set(
