This article is written by the golang tutorial column to share with you a pitfall in the for range in the go language. If you have friends who have encountered the same problem, you can refer to it! Thank you~
The pitfalls in the go language for range
If you want to get the pointer , the reason for using this method
is that the for range loop only has :=
for the first time, and =
from the second loop onwards (for the previous The variables are assigned values instead of re-initialized, so they all correspond to the same pointer); so the pointer address is the same no matter how many times it is looped;
The above is the detailed content of Record the pitfalls in for range in golang. For more information, please follow other related articles on the PHP Chinese website!

Developers should follow the following best practices: 1. Carefully manage goroutines to prevent resource leakage; 2. Use channels for synchronization, but avoid overuse; 3. Explicitly handle errors in concurrent programs; 4. Understand GOMAXPROCS to optimize performance. These practices are crucial for efficient and robust software development because they ensure effective management of resources, proper synchronization implementation, proper error handling, and performance optimization, thereby improving software efficiency and maintainability.

We need to customize the error type because the standard error interface provides limited information, and custom types can add more context and structured information. 1) Custom error types can contain error codes, locations, context data, etc., 2) Improve debugging efficiency and user experience, 3) But attention should be paid to its complexity and maintenance costs.

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),
