PHP 解压文件 ZipArchive 中文文件名丢失/乱码问题

PHP 解压文件 ZipArchive 中文文件名丢失/乱码问题     PHP 解压中文或解压文件中 文件名存在中文  

$file = '/log/你好.zip';  //文件路径 如/log/test/123.zip
$outputPath = '/opt';   //解压后存储的路径
$zip = new \ZipArchive();
$openRes = $zip->open($file);
if ($openRes === true) {
    $docnum = $zip->numFiles;
    for($i = 0; $i < $docnum; $i++) {
        $statInfo = $zip->statIndex($i,\ZipArchive::FL_ENC_RAW);
        $filename = $this->transcoding($statInfo['name']);  //转码
        if($statInfo['crc'] == 0) {
            //新建目录
            mkdir($outputPath.'/'.substr($filename, 0,-1));
        } else {
            //拷贝文件
            copy('zip://'.$file.'#'.$zip->getNameIndex($i), $outputPath.'/'.$filename);
        }
    }
    // $zip->extractTo($outputPath);
    $zip->close();
    return ['status'=>true,'path'=>$outputPath];
}
