Zip对象无效或单元化

Question

if(isset($_POST['items'])) {
    // open zip
    $zip_path = 'downloadSelected/download.zip';
    $zip = new ZipArchive();

    if ($zip->open($zip_path, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE) !== TRUE) {
       die ("An error occurred creating your ZIP file.");
     }

     foreach ($_POST['items'] as $path) {
        // generate filename to add to zip
        $filepath = 'downloads/' . $path . '.zip';
        if (file_exists($filepath)) {
                $zip->addFile($filepath, $path . '.zip') or die ("ERROR: Could not add the file $filename");
        }
        else {
                die("File $filepath doesnt exit");
                }
        $zip->close();
       } }

我收到警告:ZipArchive::addFile()[function.ZipArchive-addFile]:Zip对象无效或单元化.可能有什么问题？我尝试了很多方法但是徒劳无功.当我选择一个文件时,我能够创建并启动下载.但是,当我选择多个文件时,我会遇到上述错误.

正确缩进的力量!

您正在关闭循环中的zip文件.

如果我重新格式化你的代码,那就很明显了.

更正后的代码如下:

if(isset($_POST['items'])) {
  // open zip
  $zip_path = 'downloadSelected/download.zip';
  $zip = new ZipArchive();

  if ($zip->open($zip_path, ZIPARCHIVE::CREATE | ZIPARCHIVE::OVERWRITE) !== TRUE) {
    die ("An error occurred creating your ZIP file.");
  }

  foreach ($_POST['items'] as $path) {

    // generate filename to add to zip
    $filepath = 'downloads/' . $path . '.zip';

    if (file_exists($filepath)) {
      $zip->addFile($filepath, $path . '.zip') or die ("ERROR: Could not add the file $filename");
    } else {
      die("File $filepath doesnt exit");
    }
  }

  $zip->close();
}

库本身为您提供了一个代码来查看它失败的原因:

$ZIP_ERROR = [
  ZipArchive::ER_EXISTS => 'File already exists.',
  ZipArchive::ER_INCONS => 'Zip archive inconsistent.',
  ZipArchive::ER_INVAL => 'Invalid argument.',
  ZipArchive::ER_MEMORY => 'Malloc failure.',
  ZipArchive::ER_NOENT => 'No such file.',
  ZipArchive::ER_NOZIP => 'Not a zip archive.',
  ZipArchive::ER_OPEN => "Can't open file.",
  ZipArchive::ER_READ => 'Read error.',
  ZipArchive::ER_SEEK => 'Seek error.',
];

$result_code = $zip->open($zip_fullpath);
if( $result_code !== true ){
   $msg = isset($ZIP_ERROR[$result_code])? $ZIP_ERROR[$result_code] : 'Unknown error.';
   return ['error'=>$msg];
}
