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.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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),
