Solution to Chinese garbled characters when decompressing PHP using ZipArchive Problem

When using the ZipArchive that comes with PHP to decompress a compressed package with a Chinese file name, garbled characters will be generated. The phenomenon is as follows:

Original structure:

Decompression code:

$zip = new \ZipArchive();
$res = $zip->open('./钱学森班.zip');
if ($res !== true){    
throw new \Exception('打开压缩包失败');
}$zip->extractTo('./cache');
$zip->close();

After decompression:

Reason

The default is Windows, and Mac encodes when compressing the package For Simplified Chinese, no file conversion was performed during decompression, resulting in decompression results inconsistent with expectations

Solution

After opening the compressed package, first transcode the internal file name and directory, and then close it after transcoding Compress the package and reopen it to decompress

as follows:

$zipName = './钱学森班.zip';
$zip = new \ZipArchive();
$res = $zip->open($zipName);
if ($res !== true){
    throw new \Exception('打开压缩包失败');
}

// 加入此段↓
$fileNum = $zip->numFiles;
for ($i = 0; $i < $fileNum; $i++) {
    $statInfo = $zip->statIndex($i, ZipArchive::FL_ENC_RAW);
    $zip->renameIndex($i, iconv(&#39;GBK&#39;, &#39;utf-8//IGNORE&#39;, $statInfo[&#39;name&#39;]));
}
$zip->close();
$zip->open($zipName);
// 截至↑

$zip->extractTo($extractTo);
$zip->close();

Notes

• Because the original compressed package file is modified after transcoding, cannot be repeated Transcoding, if you don’t want to affect the original file, you need to copy it first (php-zip extension reads the file stream by itself, no need to copy)

• Use mb_detect_encoding before conversion Encoding judgment still returns UTF-8
