What is the difference between socket and swoole

Socket is the interface for tcp/ip operations provided by the system. Swoole is a php extension that encapsulates socket and provides php operation interface.

A socket is an abstraction layer through which applications can send or receive data, and can open, read, write, and close operations like files. Sockets allow applications to insert I/O into the network and communicate with other applications on the network. A network socket is a combination of IP address and port.

The transport layer implements end-to-end communication, therefore, each transport layer connection has two endpoints. So, what are the endpoints of the transport layer connection? Not the host, not the host's IP address, not the application process, not the transport layer protocol port.

The endpoint of the transport layer connection is called a socket. According to the definition of RFC793: the port number concatenated with the IP address forms a socket.

The so-called socket is actually a communication endpoint. Each socket has a socket serial number, including the IP address of the host and a 16-bit host port number, which is in the form of (host IP address: port number). For example, if the IP address is 210.37.145.1 and the port number is 23, the resulting socket is (210.37.145.1:23).

In short, socket Socket= (IP address: port number), the socket is expressed by writing the port number after the IP address in dotted decimal notation, separated by a colon or comma. Each transport layer connection is uniquely identified by the two endpoints (i.e., the two sockets) on either side of the communication.

Swoole is a PHP asynchronous network communication engine for production environments, allowing PHP developers to write high-performance asynchronous concurrent TCP, UDP, Unix Socket, HTTP, and WebSocket services.

Swoole can be widely used in the Internet, mobile communications, enterprise software, cloud computing, online games, Internet of Things (IOT), Internet of Vehicles, smart homes and other fields. Using PHP Swoole as a network communication framework can greatly improve the efficiency of enterprise IT R&D teams.

Contains the following special functions:

1. ORM-like data query, providing SQL wrapper to seamlessly combine MySQL's SQL with PHP's Array, session, and Cache.

2. App MVC layered structure, effective program structure layering, improves program maintainability and scalability, achieves low coupling, and is developed based on interfaces.

3. Integrate a large number of practical functions, such as convenient database operations, template operations, cache operations, system configuration, form processing, paging, data calling, dictionary operations, upload processing, content editing, debugging, etc.

4. The template-data reflection system can directly call data in the template and provide many tags. It can realize various updates and maintenance of the website without modifying the program and only modifying the template.

A few other functions:

1. Swoole contains a large number of classes and provides many functional extensions. Basically, most of the functional classes that can be used in web development can be used in the Swoole framework found in.

2. Swoole has a plug-in system, Fckeditor, Adodb, pscws Chinese word segmentation, Chinese full-text indexing system, the latest Key-Value database idea, TokyoTyrant, which can infinitely expand the functions of the framework.

What are the basic requirements for c language functions What are the basic requirements for c language functions Apr 03, 2025 pm 10:06 PM

C language functions are the basis for code modularization and program building. They consist of declarations (function headers) and definitions (function bodies). C language uses values ​​to pass parameters by default, but external variables can also be modified using address pass. Functions can have or have no return value, and the return value type must be consistent with the declaration. Function naming should be clear and easy to understand, using camel or underscore nomenclature. Follow the single responsibility principle and keep the function simplicity to improve maintainability and readability.

The difference between H5 and mini-programs and APPs The difference between H5 and mini-programs and APPs Apr 06, 2025 am 10:42 AM

H5. The main difference between mini programs and APP is: technical architecture: H5 is based on web technology, and mini programs and APP are independent applications. Experience and functions: H5 is light and easy to use, with limited functions; mini programs are lightweight and have good interactiveness; APPs are powerful and have smooth experience. Compatibility: H5 is cross-platform compatible, applets and APPs are restricted by the platform. Development cost: H5 has low development cost, medium mini programs, and highest APP. Applicable scenarios: H5 is suitable for information display, applets are suitable for lightweight applications, and APPs are suitable for complex functions.

C language functions are reusable code blocks. They receive input, perform operations, and return results, which modularly improves reusability and reduces complexity. The internal mechanism of the function includes parameter passing, function execution, and return values. The entire process involves optimization such as function inline. A good function is written following the principle of single responsibility, small number of parameters, naming specifications, and error handling. Pointers combined with functions can achieve more powerful functions, such as modifying external variable values. Function pointers pass functions as parameters or store addresses, and are used to implement dynamic calls to functions. Understanding function features and techniques is the key to writing efficient, maintainable, and easy to understand C programs.
