目录的递归副本 [英] Recursive Copy of Directory

问题描述

在我的旧VPS上，我使用以下代码将目录中的文件和目录复制到用户提交表单后创建的新目录中。

On my old VPS I was using the following code to copy the files and directories within a directory to a new directory that was created after the user submitted their form.

function copyr($source, $dest)
{
   // Simple copy for a file
   if (is_file($source)) {
      return copy($source, $dest);
   }

   // Make destination directory
   if (!is_dir($dest)) {
      mkdir($dest);
      $company = ($_POST['company']);
   }

   // Loop through the folder
   $dir = dir($source);
   while (false !== $entry = $dir->read()) {
      // Skip pointers
      if ($entry == '.' || $entry == '..') {
         continue;
      }

      // Deep copy directories
      if ($dest !== "$source/$entry") {
         copyr("$source/$entry", "$dest/$entry");
      }
   }

   // Clean up
   $dir->close();
   return true;
}

copyr('Template/MemberPages', "Members/$company")

但是现在在我的新VPS它只会创建主目录，但不会复制任何文件到它。

However now on my new VPS it will only create the main directory, but will not copy any of the files to it. I don't understand what could have changed between the 2 VPS's?

推荐答案

尝试这样：

$source = "dir/dir/dir";
$dest= "dest/dir";

mkdir($dest, 0755);
foreach (
 $iterator = new \RecursiveIteratorIterator(
  new \RecursiveDirectoryIterator($source, \RecursiveDirectoryIterator::SKIP_DOTS),
  \RecursiveIteratorIterator::SELF_FIRST) as $item
) {
  if ($item->isDir()) {
    mkdir($dest . DIRECTORY_SEPARATOR . $iterator->getSubPathName());
  } else {
    copy($item, $dest . DIRECTORY_SEPARATOR . $iterator->getSubPathName());
  }
}

迭代器遍历所有文件夹和子文件夹，文件从 $ source 到 $ dest

Iterator iterate through all folders and subfolders and make copy of files from $source to $dest
