Node.JS vs PHP CLI Server 简单的HTTP服务器性能测试
环境:64位Ubuntu14.04,i5-3230M
PHP5.4.31 with ZendOPcache
Node.JS 0.10.35
//t.js
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/html;charset=UTF-8'});
res.write('
res.end();
}).listen(8082, '127.0.0.1');
运行程序:
node t.js
查看系统CPU空闲率:
sar 1
压力测试,并发100,完成10万请求:
ab -c100 -n100000 http://127.0.0.1:8082/t.js
内存从11MB涨到61MB,系统CPU空闲率65%, RPS达到6049.

//t.php
运行程序:
php -S 127.0.0.1:8081 -t ./
查看系统CPU空闲率:
sar 1
压力测试,并发100,完成10万请求:
ab -c100 -n100000 http://127.0.0.1:8081/t.php
内存从19.6MB涨到20.0MB,系统CPU空闲率57%, RPS达到 11405.
结论:Node.JS和PHP CLI Server都是单进程处理 HTTP 请求,RPS上PHP几乎是Node.JS的两倍,内存占用上PHP却只有Node.JS的1/3。Node.JS值得称道的是,系统CPU空闲率要比PHP高8%左右。另外,PHP-FPM虽然不支持HTTP协议,但其处理PHP请求的性能并不会比PHP CLI Server差,而且PHP-FPM可以开启多个工作进程,充分利用多核。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
