PHP 是做前台还是后台?前端和前台的区别?

个人理解,其实这个有狭义的前端和广义的前端的区别。
狭义的前端大家已经说的很明白了,“(在浏览器里)看得见的部分”,主要的技术就是HTML, CSS, JavaScript,Flash,siverlight等等。
广义的前端,包括了服务器输出到用户浏览器的页面,也就是MVC框架中的View这一层,对应的后端是服务和数据访问。在服务器中,前端会封装了页面显示的部分逻辑,比如渲染表格时候会在这一层做个循环(当然也可以用js渲染),或者生产form。因为是在服务器端执行好了,优点是快速,安全。
当然,PHP的功能不止于输出页面,还有逻辑层,服务层和DAO,或许还有读写文件,消息队列,事件机制等等。严格意义上说,PHP做后端的事要比前端多很多。不同的公司对此可能有不同的理解,我觉得这个也没有必要较真,就算做狭义的前端的同学们了解一下php的框架也是非常有好处的。 网络程序大多都是 C/S 模式的,即客户端(Client)和服务器(Server)之间互相传数据和交互。Web 应用就是 C/S 模式的,浏览器作为一种通用的客户端,所以往往我们又用 B/S 来描述这种模式。在 Web 里面,客户端(浏览器)是前端,服务器是后端,前后相对于你(程序员)而言。

说 PHP 是做前端还是后端的我觉得都不太贴切,PHP 运行在后端(服务器端),运行的结果会送到前端(客户端,浏览器)展示出来。就像报社的编辑,在报社把文章写好,印在报纸上,然后送到你面前给你看。 同意@杨伽蓝 的狭义广义的说法。
一般认为狭义的前端是指页面展示相关的内容,包括HTML,CSS,JS等,这个大家都说的很清楚了

和同学聊天的时候发现现在很多做后端的工程师把后端也分为前端和后端,前端指和请求处理与业务逻辑联系更紧密的部分,多指PHP;后端指系统的一些支撑结构,偏向基础架构的部分,可能是由C/C++,Java等开发的。

题主指的可能是这个意思吧。 1,简明扼要回答楼主问题:
PHP 是做后台的。
前端 = 前台 = Front-end,后端 = 后台 = Back-end。

2,
楼主继续加油,好好学习下 Web 开发吧。
其实你这个问题问的实在有点不知所云,说多了怕你更想不通,所以从基础踏实学起吧! PHP大体上来说是做后端开发的,但是PHP也是前端展示的一个重要形式。
所以一般的前端开发经理,都需要懂得PHP,因为涉及到很多应用方面的问题,还有和后端的人员交流的问题。 前台不应该是个管接待登记等的漂亮妹子么~ PHP 是脚本语言是做后台的,处理数据以及交换数据 其实这些概念都是相对来说的... 最终展示结果的那一端(离你最近的), 就是所谓的前端.

以web 请求为标准, PHP就是后端, 因为运行在服务器上, js, css, html就是前端(会在浏览器中被执行和解析, 渲染等). PHP 是做后台的。前端开发主要是静态用户界面加上一些动态效果,不涉及数据逻辑!例如:一个登陆页面: 前端开发只要做好静态页面部分 ,加上鼠标移入输入框、移出输入框的颜色变化;但是输入用户名、密码 后登录系统的话要连接数据库,这个就需要后台开发做逻辑处理了!PHP快速开发实战视频课程 前台和后台的区别,就是算代码解析和运行的位置,解析和运行于服务器的就是后台,其他就是前台。
前端和前台的区别,个人认为,前台范围更广,美工、HTML标签、js编程都属前台。而前端只管编程类的工作。

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.

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.

Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Apr 08, 2025 am 12:03 AM

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

What is the difference between include, require, include_once, require_once? What is the difference between include, require, include_once, require_once? Apr 05, 2025 am 12:07 AM

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.
