Article Introduction：Core points PSR-3, a common log object interface, allows developers to write reusable code without relying on any specific log implementation, thereby improving compatibility between different log libraries in PHP. The PSR-3 interface provides eight methods to handle messages of different severity levels, and a common log() method that can receive any severity levels. Its design is to solve the problem of log implementation incompatibility. Although PSR-3 has many benefits, some log libraries do not support it natively. However, developers can create PSR-3 compliant adapters by leveraging the adapter pattern and extending the AbstractLogger class provided in the Psr/Log library. Many major PHP projects

Article Introduction：How to create and consume SOAP or XML-RPC network services using PHP? 1. For SOAP services, use the SoapServer class to define processing logic on the server side and generate WSDL files, bind classes or functions to respond to requests; use the SoapClient class to call remote methods on the client side and ensure that the php_soap extension is enabled. 2. For XML-RPC services, you need to use XML_RPC3 and other libraries to register methods on the server side and process requests, and send XML-RPC messages to the client for calls. 3. Common precautions include: enabling necessary extensions, disabling WSDL cache for development, correctly handling errors and exceptions, using debugging tools to view request content, ensuring security and checking

Article Introduction：In PHP, latestatic binding solves the limitations of self:: in inheritance through the static:: keyword. When using self::, it always points to the class that defines the method, not to call or inherit it; while static:: determines the target class at runtime, thus correctly referring to the subclass that is actually called. For example, if a method defined in the parent class is called by a subclass, self::class returns the parent class name, and static::class returns the child class name. 1. Use self:: to strictly refer to the current class definition; 2. Use static:: to support inheritance and allow subclass rewriting behavior; 3. Common application scenarios include factory mode
