1. The first choice for the Laravel MySQL Vue/React combination in the PHP development question and answer community is the first choice for Laravel MySQL Vue/React combination, due to its maturity in the ecosystem and high development efficiency; 2. High performance requires dependence on cache (Redis), database optimization, CDN and asynchronous queues; 3. Security must be done with input filtering, CSRF protection, HTTPS, password encryption and permission control; 4. Money optional advertising, member subscription, rewards, commissions, knowledge payment and other models, the core is to match community tone and user needs.

To collect user behavior data, you need to record browsing, search, purchase and other information into the database through PHP, and clean and analyze it to explore interest preferences; 2. The selection of recommendation algorithms should be determined based on data characteristics: based on content, collaborative filtering, rules or mixed recommendations; 3. Collaborative filtering can be implemented in PHP to calculate user cosine similarity, select K nearest neighbors, weighted prediction scores and recommend high-scoring products; 4. Performance evaluation uses accuracy, recall, F1 value and CTR, conversion rate and verify the effect through A/B tests; 5. Cold start problems can be alleviated through product attributes, user registration information, popular recommendations and expert evaluations; 6. Performance optimization methods include cached recommendation results, asynchronous processing, distributed computing and SQL query optimization, thereby improving recommendation efficiency and user experience.

To allow PHP services to pass through the Windows 11 firewall, you need to create inbound rules to open the corresponding port or program. 1. Determine the port that PHP is actually listening. If the built-in server is started with php-Slocalhost:8000, the port is 8000. If using Apache or IIS, it is usually 80 or 443. 2. Open the advanced settings of "WindowsDefender Firewall", create a new inbound rule, select "Program" or "Port", fill in the PHP or Web server path or specify the port number. 3. Select Allow Connections, check the applicable network configuration file, name the rules and add a description. The IP addresses that are allowed to access, such as local network or specific IP, can be restricted through the scope. Safety

Why do I need SSL/TLS encryption MySQL connection? Because unencrypted connections may cause sensitive data to be intercepted, enabling SSL/TLS can prevent man-in-the-middle attacks and meet compliance requirements; 2. How to configure SSL/TLS for MySQL? You need to generate a certificate and a private key, modify the configuration file to specify the ssl-ca, ssl-cert and ssl-key paths and restart the service; 3. How to force SSL when the client connects? Implemented by specifying REQUIRESSL or REQUIREX509 when creating a user; 4. Details that are easily overlooked in SSL configuration include certificate path permissions, certificate expiration issues, and client configuration requirements.

Methods that implement Excel pivot table functions similar to MySQL mainly include using CASE or IF statements to combine aggregate functions for row conversion. 1. Use CASEWHEN to realize static row-to-column conversion, which is suitable for situations where column values are known to be converted. New columns are generated for different values and data are summarized through SUM (CASEWHEN...). 2. Generate columns dynamically, suitable for situations where specific values are uncertain. You need to obtain a unique value before constructing a CASE expression. Usually, it is combined with stored procedures or application layer logic to splice and execute SQL strings; 3. Use IF functions to simplify syntax to achieve the same effect as CASE but the writing method is more compact. In actual applications, if the dimension is fixed, the column can be hard-coded directly. If the dimension changes frequently, it is recommended to use scripts or store them.

Apache can achieve load balancing by enabling mod_proxy and mod_proxy_balancer modules. 1. Enable modules: including mod_proxy, mod_proxy_http, mod_proxy_balancer and mod_lbmethod_byrequests; 2. Configure virtual host files, use BalancerMember to define back-end servers, ProxySet sets load algorithms, ProxyPass and ProxyPassReverse forwarding requests; 3. Optional configurations include setting weights, health checks, session hold and timeout control; 4. Finally test and reload Apache

There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2. Passed through a web server (such as SetEnv of Apache or fastcgi_param of Nginx); 3. Use putenv() function in PHP scripts. Among them, php.ini is suitable for global and infrequently changing configurations, web server configuration is suitable for scenarios that need to be isolated, and putenv() is suitable for temporary variables. Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en
