HomeBackend DevelopmentPHP TutorialPHP 是做前台还是后台?前端和前台的区别?

回复内容:

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。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
