What should I do if Chinese php is sent to the background with garbled characters?

Solution to the Chinese garbled problem of php file upload background storage:

php file upload background processing explanation:

After the user uploads the file ( I use uploadify2.3 for the front end. I hope to save it according to its original file name (sometimes in Chinese). Only using PHP's move_uploaded_file command will cause garbled characters (I am a Ubuntu server). You need to use icotargetFile=iconv(′UTF−8′,′GB2312//IGNORE′,targetFile) first; without IGNORE, iconv will fail to convert the character - (horizontal bar) and automatically truncate it afterwards. For example:

iconv('UTF-8', 'GB2312//IGNORE', "博客—yet"); // 输出"博客yet"
iconv('UTF-8', 'GB2312//IGNORE', "博客—yet"); // 输出"博客"

So the correct storage method is:

$targetFile = iconv('UTF-8', 'GB2312//IGNORE', $targetFile); // UTF8转GB2312
move_uploaded_file($tempFile, $targetFile);  // 服务器把文件暂时放在$tempFile

Because transcoding will lose characters, we need to save the new file name. In order to determine which characters are lost, I used this back and forth Conversion trick:

$targetFile = iconv('GB2312', 'UTF-8//IGNORE', $targetFile );

php file download background processing explanation:

When to use GB2312 and when to use UTF8 is important.

In addition, ob_clean() and flush() are the key to whether the downloaded file is garbled
