Tips to solve Chinese garbled characters written in txt files by PHP
With the rapid development of the Internet, PHP, as a widely used programming language, is used more and more used by developers. In PHP development, it is often necessary to read and write text files, including txt files that write Chinese content. However, due to encoding format problems, sometimes the written Chinese will appear garbled. This article will introduce some techniques to solve the problem of Chinese garbled characters written into txt files by PHP, and provide specific code examples.
Problem Analysis
In PHP, the encoding format of text files is usually UTF-8. When writing Chinese content, due to encoding conversion, Chinese characters may be garbled in the file. show. This is because the default encoding of PHP itself is ISO-8859-1, and the encoding of the txt file is UTF-8. If the encoding is not converted, Chinese characters will be displayed incorrectly.
Solution
In order to solve the problem of Chinese garbled characters written in txt files by PHP, you can use the following techniques:
- Use the mb_convert_encoding function for encoding Conversion
mb_convert_encoding is a commonly used function in PHP, used to encode and convert strings. We can convert the content to be written into the txt file into UTF-8 encoding before writing it to avoid the problem of Chinese garbled characters.
$content = "中文內(nèi)容";
$content = mb_convert_encoding($content, 'UTF-8');
$file = fopen("sample.txt", "w");
fwrite($file, $content);
fclose($file);- Set the encoding format of the file stream
When opening the file stream, you can avoid the Chinese garbled problem by specifying the opening mode and encoding format .
$file = fopen("sample.txt", "w,ccs=UTF-8");
$content = "中文內(nèi)容";
fwrite($file, $content);
fclose($file);- Use UTF-8 BOM mark
Sometimes, in the UTF-8 encoded txt file, add BOM (Byte Order Mark ) tag helps other programs correctly parse the file contents. BOM markers can be added to the beginning of the file before writing the content.
$file = fopen("sample.txt", "w");
$content = "?中文內(nèi)容";
fwrite($file, $content);
fclose($file);Summary
Through the above techniques, you can effectively solve the problem of Chinese garbled characters written in txt files by PHP. In actual development, the appropriate method is selected according to the specific situation to handle Chinese encoding conversion, thereby ensuring that the Chinese content written into the txt file is displayed normally. I hope the content of this article will be helpful to PHP developers who encounter problems with Chinese garbled characters.

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
What are the best practices for writing clean and maintainable PHP code?
Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
