php 解压 zip 压缩包

// 将vendor/chumper/zipper/src/Chumper/Zipper/Repositories/ZipRepository.php种的each方法修改为以下：
public function each($callback)
{
      for ($i = 0; $i < $this->archive->numFiles; ++$i) {
          //skip if folder
          $stats = $this->archive->statIndex($i);

          if ($stats['size'] === 0 && $stats['crc'] === 0) {
              continue;
          }
          // 这里做了修改
          $rawName = $this->archive->getNameIndex($i, ZipArchive::FL_ENC_RAW);
          $encode = mb_detect_encoding($rawName, array("ASCII",'UTF-8',"GB2312","GBK",'BIG5'));
          $rawName = iconv($encode, 'UTF-8', $rawName);

          call_user_func_array($callback, [
              $stats['name'], $rawName
          ]);
      }
}

// 将vendor/chumper/zipper/src/Chumper/Zipper/Zipper.php中extractFilesInternal方法修改为以下：
private function extractFilesInternal($path, callable $matchingMethod)
{
      $self = $this;
      // 添加一个中文名参数
      $this->repository->each(function ($fileName, $CNName) use ($path, $matchingMethod, $self) {
          $currentPath = $self->getCurrentFolderWithTrailingSlash();
          if (!empty($currentPath) && !starts_with($fileName, $currentPath)) {
              return;
          }

          $filename = str_replace($self->getInternalPath(), '', $fileName);
          if ($matchingMethod($filename)) {
              $self->extractOneFileInternal($fileName, $CNName, $path);
          }
      });
}

// vendor/chumper/zipper/src/Chumper/Zipper/Zipper.php中extractOneFileInternal方法修改为以下：
private function extractOneFileInternal($fileName, $CNName, $path)
{
      $tmpPath = str_replace($this->getInternalPath(), '', $CNName);  // 用手动转码的中文文件名命名

      // We need to create the directory first in case it doesn't exist
      $dir = pathinfo($path.DIRECTORY_SEPARATOR.$tmpPath, PATHINFO_DIRNAME);
      if (!$this->file->exists($dir) && !$this->file->makeDirectory($dir, 0755, true, true)) {
          throw new \RuntimeException('Failed to create folders');
      }

      $toPath = $path.DIRECTORY_SEPARATOR.$tmpPath;
      $fileStream = $this->getRepository()->getFileStream($fileName);  // 用系统转码的文件名获取资源
      $this->getFileHandler()->put($toPath, $fileStream);
}
