The example in this article describes the insert database operation function based on the thinkPHP class. Share it with everyone for your reference, the details are as follows:
Insertion database operation based on TP class
/************************** * 插入互动专家的数据 * * @param object $model 实例化的模型 * @param array $Model 获取到的专家数据 * @param int $result 插入成功后返回的id * @date 2016/02/19 * @write zss ****************************/ private function collect_sp_t_insert($model){ $model = D($model); //删除主键,防止此操作成为更新操作 unset( $_POST[$model->getPk()]); //回调处理post数据 if (method_exists($this, '_tigger_post')) { $this->_tigger_post($_POST); } //reate数据 if(false === $model->create()) { $this->error($model->getError()); } //保存当前数据对象 if ($result = $model->add()) { //保存成功 // 回调接口 if (method_exists($this, '_tigger_insert')) { $this->_tigger_insert($result); } } }
I hope this article will be helpful to everyone’s PHP program design based on the ThinkPHP framework.

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(

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.
