Php Zip文件需要包含空文件夹

我目前有以下目录结构：

upload-here
upload-here/258/Image1.jpg
upload-here/259/Image2.jpg
upload-here/260/NO IMAGE
upload-here/261/somepicturename.jpg

等等。我正在使用下面显示的代码通过压缩上传文件夹来备份上传文件夹

<?php
// Get real path for our folder
$rootPath = realpath('/full-path-to/upload-here/');

// Initialize archive object
$zip = new ZipArchive();
$zip->open('upload-here.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);

// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($rootPath),
    RecursiveIteratorIterator::LEAVES_ONLY
);

foreach ($files as $name => $file)
{
    // Skip directories (they would be added automatically)
    if (!$file->isDir())
    {
        // Get real and relative path for current file
        $filePath = $file->getRealPath();
        $relativePath = substr($filePath, strlen($rootPath) + 1);

        // Add current file to archive
        $zip->addFile($filePath, $relativePath);
    }
}
// Zip archive will be created only after closing object
$zip->close();
?>

您可以检查文件夹是否为空，然后使用[addEmptyDir（）][1]将其添加到存档：

    foreach ($files as $name => $file)
    {
     $filePath = $file->getRealPath();
     $relativePath = substr($filePath, strlen($rootPath) + 1);
    // Skip directories (they would be added automatically)
    if (!$file->isDir())
    {
        // Add current file to archive
        $zip->addFile($filePath, $relativePath);
    } else {
        if(count(glob($name."/*")) == 0) {
           $zip->addEmptyDir(basename($name));
    }
  }
}

请试一试。您可以获取包含空文件夹的zip文件

foreach ($files as $name => $file) {
$filePath = $file->getRealPath();
$relativePath = substr($filePath, strlen($rootPath) + 1);
// Skip directories (they would be added automatically)
if (!$file->isDir()) {
    // Add current file to archive
    $zip->addFile($filePath, $relativePath);
} else {
    if($relativePath !== false)
        $zip->addEmptyDir($relativePath);
}}

似乎仍在跳过空文件夹（刚刚测试过，zip只包含包含文件的文件夹，没有空文件夹；您尝试过$relativePath和$filePath吗？并且$name变量只包含文件名还是完整路径？我还编辑了代码，在某种情况下遗漏了一个否定项。因此，请参阅EditsHanks以获取帮助，很遗憾，上述操作现在只会导致zip文件为空。）使用的y变量如下所示etc@user6796243我对代码做了一些更改，现在就试试。另外，我知道它们只是使用的变量，但我想知道它们的值。似乎仍然跳过了空文件夹（刚刚测试过，zip只包含包含文件的文件夹，没有空文件夹；您尝试过$relativePath和$filePath吗？并且$name变量只包含文件名还是完整路径？我还编辑了代码，在某种情况下遗漏了一个否定项。因此，请参阅EditsHanks以获取帮助，很遗憾，上述操作现在只会导致zip文件为空。）使用的y变量如下所示etc@user6796243我对代码做了一些更改，现在就试试。另外，我知道它们只是使用的变量，但我想知道它们的值。很酷，很高兴听到：）很酷，很高兴听到：）
