What should I do if the output file name displayed in Windows shows garbled characters?

My code:

$filesss = glob('./pic/*.jpg');
print_r($filesss);

When running the program on a Windows environment, the output file name displays as garbled text.

Invalid character display reason:

On Windows, PHP uses the system's default encoding by default when processing file names; this can cause file names containing Chinese characters or other non-ASCII characters to be displayed as garbled text during output.

Solution:

Use iconv() The function converts the file name into an appropriate encoding before outputting it.

Final code:

$filesss = glob('./pic/*.jpg');

// 遍历文件数组，并使用 iconv 函数转换编码
foreach ($filesss as $file) {
    // 将文件名从系统默认编码转换为 UTF-8
    $file_utf8 = iconv("CP936", "UTF-8", $file); // CP936 是 Windows 下的默认中文编码

    // 输出转换后的文件名
    echo $file_utf8 . "\n";
}

iconv("CP936", "UTF-8", $file)It converts the Windows default Chinese character encoding (CP936, also known as GBK) to UTF-8 encoding, ensuring that the file names are displayed correctly.

If the original encoding of the file name is not CP936 but another encoding (e.g., UTF-8), you should adjust it accordingly based on the actual situation. iconv() Parameters in a function.
