How to avoid garbled characters when writing txt files with PHP

In PHP, when we write text data to a txt file, garbled characters sometimes occur. This kind of problem is usually caused by inconsistent coding. Here are some specific methods and code examples to avoid garbled characters when PHP writes txt files.

First, we need to determine what file encoding is used. Generally speaking, UTF-8 encoding is used in PHP. Before writing the txt file, we can set the encoding method of the file to ensure that the written data is in accordance with the specified encoding method.

Next, we need to use PHP functions to perform file writing operations. When writing files, you need to use the correct encoding method to process text data to avoid garbled characters. The following is a sample code:

<?php

$file = 'example.txt';
$data = '这是一段中文文字';

// 打开文件，以追加的方式写入数据
$handle = fopen($file, 'a');

// 将数据以UTF-8编码写入文件
fwrite($handle, iconv('UTF-8', 'GB2312//TRANSLIT', $data));

// 关闭文件
fclose($handle);

echo '数据已成功写入到文件中！';
?>

In the above example, we use the iconv function to convert UTF-8 encoded data to GB2312 encoding, and then write it to the txt file . This ensures that the data is written in the correct encoding and avoids garbled characters.

In addition, you can also specify the encoding method when opening the file, for example, use the utf8_encode function to specify UTF-8 encoding:

$handle = fopen($file, 'a');
fwrite($handle, utf8_encode($data));
fclose($handle);

Through the above method, we can avoid Garbled characters occur when PHP writes txt files. In practical applications, the appropriate encoding method can be selected to process text data according to specific circumstances to ensure that the data can be correctly written to the file.
