  • Implement associated data query and filtering under complex conditions in Laravel Eloquent
    Implement associated data query and filtering under complex conditions in Laravel Eloquent
    This article will explore in-depth how to implement flexible conditional association queries through the powerful functions of the application layer (especially LaravelEloquent) when standard foreign key constraints cannot meet the data association requirements under complex conditions in relational databases such as MySQL. We will focus on how to use Eloquent's preloading (eagerloading) to cooperate with conditional constraints to efficiently retrieve and filter out related data that conforms to specific business logic, so as to achieve behavior similar to "conditional foreign keys" without modifying the database structure.

  • How to configure Windows 11 firewall to allow PHP services PHP port open and secure settings
    How to configure Windows 11 firewall to allow PHP services PHP port open and secure settings
    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
