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:

1. 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 = "中文内容";
$content = mb_convert_encoding($content, 'UTF-8');
$file = fopen("sample.txt", "w");
fwrite($file, $content);
fclose($file);

2. 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");
$content = "中文内容";
fwrite($file, $content);
fclose($file);

3. 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");
$content = "中文内容";
fwrite($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.
