Common mistakes in PHP-based mall development

With the development of the Internet, e-commerce has increasingly become the main way for people to purchase goods. The construction of shopping malls is an important support for the widespread popularity of e-commerce. As a popular programming language, PHP is widely used in the development of shopping malls. However, during the mall development process, we often overlook some details, leading to some common mistakes. Below, this article uses some cases to discuss common mistakes in PHP mall development.

1. Unreasonable database design

The database is the core of the mall, and its design is the key to mall development. However, in mall development, many developers do not have enough experience and skills, and the designed database often has problems, resulting in a decrease in mall performance and efficiency. Common errors include the following:

①Table attributes do not correspond

When designing the table structure, problems often arise that table attributes do not correspond. For example, the attributes in a table are Fields of type int are processed into string types in the program, resulting in some unexpected errors.

②Field redundancy

When designing the table structure, developers often like to add some repeated fields to different tables. Although this can facilitate querying, it will lead to database redundancy. Otherwise, the database performance will be reduced.

③Excessive indexes

Although indexes are a necessary means to improve query efficiency when designing the table structure, too many indexes will cause the database table to be too large, affecting query efficiency.

Therefore, in mall development, a well-designed database is crucial.

2. Insufficient security measures

In mall development, considering the security of user data, the importance of security measures is self-evident. However, in actual development, the following often occur Common security omissions:

①SQL injection

SQL injection is to bypass the security check of the application and achieve attacks on the database by injecting malicious code into SQL statements. In mall development, filtering and escaping user-entered data is an effective measure to avoid SQL injection.

②XSS attack

XSS attack is an attack method that steals user information by embedding malicious code into the page. In mall development, XSS attacks can be effectively avoided by filtering and escaping user input.

③Password encryption

In mall development, the encryption of user passwords is an important means to ensure the security of user information. Using salted hashing algorithm to encrypt user passwords can avoid user information security issues caused by password leakage.

3. Performance issues

The mall is a huge system, and its performance optimization is an issue that developers need to focus on and solve. During the mall system development process, because many developers do not have a deep understanding of system performance optimization methods, they often make the following common mistakes:

①Excessive database queries

When developing the mall , developers usually use tools such as ORM to access the database more times. Although the logic is relatively clear for developers, system performance will decrease due to the limitation of the number of database connections.

②File upload

During the development process of the mall, it is often necessary to upload files. If the uploaded file is too large, it will cause the system processing speed to slow down or even the program to crash.

Therefore, in mall development, it is necessary to consider system performance optimization.

4. Wrong framework selection

The resources required by the developer city are very rich. However, developers often make the following common mistakes when choosing a framework:

①Choose the wrong framework

The mall is a large system. When developers choose a framework, they should first consider the scalability and ease of use of the framework. If you choose the wrong framework, it will bring inconvenience to later development and maintenance.

②Framework upgrade issues

The framework should be updated and maintained for a long time to ensure the security and stability of the system. If the framework is not upgraded in time, it will lead to vulnerabilities and errors in the application.

To sum up, there are many mistakes that are easy to make in mall development, including many details. During the development process, we should be vigilant enough and pay attention to details to ensure the stability and reliability of the mall system and improve user satisfaction.
