php&&页面静态化

Jun 23, 2016 pm 01:28 PM

页面静态化,主要是出于两个方面的考虑。
    第一:访问html页面的速度比访问php页面的速度快。在访问php页面时候,需要对php进行解析。访问html时候,直接浏览器可以解析出来。特别是PV量很大的情况下,同时在线访问量很大的前提下。可以通过Apache自带的ab.exe工具做一个简单有效的压力测试。
    在apache / bin/ab.exe  可以做压力测试,该工具可以模拟多人,并发访问某个页面
 基本的用法
  ab.exe ?n 10000 ?c 1000  http://localhost/test.php
  -n 表示请求多少次
 -c 表示多少人


    第二:有利于SEO优化。SEO搜索引擎,更有利于网络爬虫的搜索。目前大多数门户网站,新浪,搜狐应该都是采用的页面静态化或者伪静态化技术处理。以提高搜索引擎爬取跟排名。
   静态化有利于SEO的原理:动态化php或者jsp网站一般都会给浏览者对应的权限,而静态化页面则不存在权限这一关。而网络爬虫,搜索引擎相当于是以游客的身份来爬取网页信息。所以静态化页面更有利于被搜索引擎给抓取。


     最后一个静态化处理的网站,安全性更高。而且就算是发生数据库错误,也不会对用户造成太大的影响。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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,

How does session hijacking work and how can you mitigate it in PHP? 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.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. 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::). 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.

What is REST API design principles? What is REST API design principles? Apr 04, 2025 am 12:01 AM

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

How do you handle exceptions effectively in PHP (try, catch, finally, throw)? How do you handle exceptions effectively in PHP (try, catch, finally, throw)? Apr 05, 2025 am 12:03 AM

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

What are anonymous classes in PHP and when might you use them? What are anonymous classes in PHP and when might you use them? Apr 04, 2025 am 12:02 AM

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
