使用 PHP 7 给 Web 应用加速
##PHP 20周年了！？？**PHP 首发通告，1995年6月8日****发布于 COMP.INFOSYSTEMS.WWW.AUTHORING.CGI** 主题：正式宣布：个人主页工具（Personal Home Page Tools） 正式宣布个人主页工具（PHP 工具）1.0 版本 此工具是一组用 C 语言写的轻量的 cgi 二进制文件。他们能运行许多功能，包括： - 在你的私有日志文件记录页面访问情况 - 实时查看日志信息 - 提供查看日志信息的友好接口 - 在你的页面展示最近一次的访问信息 - 完整的每天及总体访问统计 - 依据用户的域名限制其访问 - 依据用户的域名为页面提供密码保护 - 依据用户的电子邮箱地址追踪其访问情况 - 支持追踪引荐 URL 的 HTTP_REFERER - 无需服务器支持即可运行 SSI (server-side includes) - 支持不记录特定域名（比如，你自己的）的访问信息 - 轻易地创建并展示表格 - 支持在后续的文档中使用表格信息 使用该工具，你不需要： - 你不需要访问根目录??工具安装在 ~/public_html 目录 - 你不需要在服务器启用 SSI (server-side includes) - 你不需要使用 Perl 或 Tcl 或其他任何脚本解释器 - 你不需要访问 httpd 日志文件 使用该工具的唯一条件是你能够运行自己的 cgi 程序。如果你不知道这是什么意思，可以询问系统管理员。 借助该工具，你还可以在两分钟内实现留言板，或其他任何用于写入信息并向访客展示的表格。 该工具不受版权限制，遵循 GNU 公共许可证。是的！该工具完全免费！ 查看该工具的完整演示，请访问：http://www.io.org/~rasmus。 -- Rasmus Lerdorf rasmus@io.org http://www.io.org/~rasmus## 用于 Web 应用的 C API void Cos(void) { Stack *s; char temp[64]; s = Pop(); if(!s) { Error("Stack error in cos"); return; } sprintf(temp,"%f",cos(s->douval)); Push(temp,DNUMBER); }###于是乎，你可以这样使用它： <html><head><title>Cos Example</title></head> <body><h1 id="Cos-Example">Cos Example</h1> <?echo Cos($input)> </body></html>##PHP7#####?

How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,

Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
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.

Explain late static binding in PHP (static::).
Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
