本文为大家介绍学习php前需要掌握的基础知识。很多人认为php可以从零基础开始学习,也就是不用学其他任何东西就可以直接去学php。的确,php入门简单,与其他知识也不挂钩,可以零基础学起,不需要具备其他知识。但是以我看来,学习php前还是得要掌握一些有关网页制作方面基础知的。学习php前,个人推荐是:hmtl -> css -> javascript -> mysql(也就是SQL语句) -> php。

html,css,javascript主要是用来做前台页面的,有人会问,既然我是学php,做的是后台程序,为什么要学前台制作呢?再说,大公司对于前台,后台,美工等不都有明确分工吗,还用的着我去写?是的,但是那是大公司,对于小公司来讲这些都是要一个人完成的。从页面设计,页面布局,美工,再到后台处理都是一个人或者几个人完成,没有明确的分工。所起必须前台,后台都会。在大公司里面,虽然有明确的分工,前台的这些东西虽然不要求你写,但是你必须看的懂。

mysql要掌握的就是sql语句,无非就是增、删、该、查,还有数据库优化等,这些比较简单,学起来也比较快,也是必须要掌握的知识。

至于ajax,jquery这些知识,当你的php学到一定程度的时候,可以考虑去学这些,因为在很多大型项目里面都要用到ajax,特别是聊天室。

下面列出学习php需要做到的:

1,保证你在手册的帮助下能看懂PHP代码。
2,保证你可以基本使用MySQL,常用的查询,包括联合查询都要会。MySQL的安装和用户权限配置要会。
3,保证你熟练使用table,理解HTML的数据组织和显示逻辑。
4,保证你理解CSS并可以进行p+CSS的布局,掌握 p , UL , DL , SPAN , P 等常见标记。(如果是专业人员,还要学习浮动,定位,lightbox等)。
5,保证你可以写常用的Javascript代码,并开始学习Javascript的库,例如Jquery。学习JS的库记住不要一下子去看源代码,先看手册然后根据例子学习,学会调用就可以了。(专业前台要研究库文件)。

1~5完成后,你就掌握了基本功,并且具备了单个文件处理问题的能力。这个时候开始学习业务逻辑。什么业务逻辑呢,就是通过代码的组织做出一个一个使用的功能。最基本的就是留言本了。这个部分最重要的就是理解,网站显示习惯,设置习惯,管理习惯,用户发布习惯。

6,熟练编写 留言本。可以熟练地通过几个PHP文件来实现小功能。比如,那些文件用来显示,哪些文件用来管理,哪些文件用来发布内容。并且粗略了解了会员功能。(可以下载留言本程序研究学习)。

7,开始接触大点的项目。先了解网站的网页流程。培养流程思路。这个时候,可以多装几个开源的PHP产品(包括国内外的),例如Discuz,DeDeCMS,Drupal等等。先不看这些产品的核心代码。看些配置,安装,模板的应用和接口。

8,开始了解网站业务架构,包括前台,后台,会员,数据流(用户到数据库,数据库到用户)。熟练掌握流程设计,比如要增加一个图片上传功能,需要几个文件。

9,找工作进行实践,一开始不要太挑剔,但是一定要找让你发挥的公司,开始接触客户需求,如何整理文档,解决bug。

10,在工作半年到一年左右,开始进行总结,根据选择的公司和你所做的应用,开始总结开发模式,模板引擎,数据库设计,等

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,
