Detailed introduction to the processes and precautions before and after PHP development

With the continuous development of the Internet, the demand for website applications is increasing day by day. Therefore, PHP has become one of the most popular programming languages ​​on the server side. Compared with other languages, PHP is easier to develop front-end and back-end, and is suitable for the development of small websites and the information construction of small and medium-sized enterprises.

This article will introduce in detail the process and precautions for PHP development front-end and back-end.

1. The front desk part

The front desk part is the main body of the website and the place where users directly access it. Usually includes the homepage, products, news, contact us, help center and other pages of the website. Its function is to directly transmit website information to the outside world. The following is the main process of front-end development.

1. Requirements Analysis

Before any development, you first need to understand the needs of the owner, analyze user roles, formulate development plans, website structure, data table design, etc. Plan development plans by asking questions and gathering needed information.

2. Interface design

The interface design of the website is an important part of front-end development. Generally, interface design requires beautiful appearance, reasonable color matching, reasonable layout, etc. For large website needs, independent UI designers are often required to participate.

3. Page production

On the basis of obtaining the UI image design provided by the designer, it is necessary to produce the html and CSS code of the web page, data interface development, and JavaScript interactive effects implementation, etc.

4. Review testing

Review testing is an important part of front-end development. It can avoid negative impacts on users due to program vulnerabilities. This stage requires developers to use professional tools to conduct security testing of the code and check the stability, compatibility, performance and other aspects of the code.

5. Release and launch

After the development of the front-end website is completed, you need to use FTP and other tools to upload the website program files to the server. At the same time, it is necessary to formulate a good SEO plan so that search engines can better crawl and index website content and increase user visits.

2. Backend development

Backend development is one of the core parts of the website. It is an important management area of ​​the website and provides back-end management functions of data for the website. If the front desk is the image display of the website, then the back desk is the soul of the website. The following is the main process of backend development:

1. Requirements analysis

Before proceeding with backend development, the owner's needs need to be carefully analyzed. The backend generally includes modules such as user management, information management, and data statistics.

2. Database design

Backend development is inseparable from the database. Designing the database needs to follow rules such as data integrity, data consistency, and data storage, and propose clear tables according to needs. structure and design.

3. Function development

Based on the results of demand analysis, start the development of backend functions. Common background functions are generally CRUD (add, delete, modify and query) operations. During development, the operation logic needs to be defined to make all data addition, deletion, modification and query operations standardized and efficient.

4. System Security

Website backend development needs to guard against security issues such as SQL injection, XSS attacks, and CSRF attacks. Developers need to conduct security testing on the code and modify vulnerable codes and functions to improve the security of the program.

5. Review Test

After the backend function development is completed, review testing is required. The development team needs to deploy the website system in a test environment for testing, verify the stability and availability of the system, and ensure that the system can meet the needs of the owner.

6. Publish and go online

After the development of the backend website is completed, it will be released online on the basis of ensuring stability and security. At this time, you also need to consider data backup and recovery to avoid extreme data loss.

Summary:

The construction of a website is inseparable from the front and backends. They complement each other and are the core components of the entire ecosystem of the website. In the front-end part, user needs and user experience need to be considered; in the back-end part, the functionality and security of the system need to be focused to provide users with better services.
