Introduction to troubleshooting and solutions for PHP mall SKU management
Abstract:
With the rapid development of e-commerce, more and more malls use PHP As a development language, SKU management is one of the core parts of the mall. However, as the scale of the mall increases, SKU management faces more and more problems, such as inventory errors, price anomalies, etc. This article will introduce you to some common SKU management problems and provide corresponding solutions.
Keywords: PHP mall, SKU management, troubleshooting, solutions
1. Problem 1: Inventory error
In a mall, inventory error is one of the most common problems . In the PHP mall, inventory errors usually manifest as inconsistencies between the displayed inventory number and the actual inventory. There are many reasons for this problem, which may be caused by program logic errors, inconsistent database reading and writing, or concurrent operations.
Solution:
- Check the program logic: First, you need to check whether there are logic errors in the PHP program, such as not having the correct judgment conditions when updating the inventory number or adding or subtracting the inventory number. A calculation error occurred. You can use debugging tools to locate the problem.
- Check database read and write: Secondly, you need to check whether the database read and write operations are correct. You can identify the problem by monitoring the read and write operations of the database and comparing the difference between the actual inventory and the displayed inventory. If you find that there are read and write inconsistencies in the database, it may be caused by concurrent operations. You can consider locking or using transactions to ensure data consistency.
2. Problem 2: Abnormal prices
In shopping malls, abnormal prices are also a common problem. In the PHP mall, price anomalies may be manifested in the product selling price being inconsistent with the displayed price or the price being a negative number. There are many reasons for this problem, such as program logic errors, database read and write inconsistencies, or data calculation errors.
Solution:
- Check the program logic: First, you need to check whether the price logic in the PHP program is correct. For example, whether the correct algorithm is used when calculating the selling price of goods, and whether discount information such as coupons is considered. The correctness of the program logic can be verified through debugging tools.
- Check database read and write: Secondly, you need to check whether the database read and write operations are correct. You can identify the problem by monitoring the read and write operations of the database and comparing the difference between the actual price and the displayed price. If you find that there are inconsistencies in reading and writing in the database, you can consider locking or using transactions to ensure data consistency.
Summary:
In PHP mall, SKU management is an important and complex issue. In order to solve problems such as inventory errors and price anomalies, we need to investigate from two aspects: program logic and database reading and writing. By checking the program logic and database read and write operations, we can locate the problem and implement corresponding solutions. At the same time, you also need to pay attention to the inconsistencies in reading and writing that may be caused by concurrent operations, and take corresponding measures to ensure data consistency. Through continuous optimization and troubleshooting, we can improve the stability and user experience of the mall and provide users with a better shopping experience.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

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),
