php删除特定文件夹及其所有内容

Question

我正在使用php删除包含已删除帖子的图像的文件夹.我正在使用下面的代码,我在网上找到并做得很好.

我想知道如果其中还有其他文件夹,我怎么才能删除文件夹中的特定文件夹.

当我使用下面的代码时,怎么可能这样做？使用:/ dev/images/norman/8 - >不会删除文件夹8使用:/ dev/images/norman/ - >将删除所有文件夹

Eg:
/dev/images/norman/8 -> I need to delete only this folder
/dev/images/norman/9
/dev/images/norman/10
/dev/images/norman/11
/dev/images/norman/12

<?php
$path = $_SERVER['DOCUMENT_ROOT'].'/dev/images/norman/8';

emptyDir($path);

function emptyDir($path) { 

    // INITIALIZE THE DEBUG STRING
    $debugStr  = '';
    $debugStr .= "Deleting Contents Of: $path<br /><br />";

    // PARSE THE FOLDER
    if ($handle = opendir($path)) {

        while (false !== ($file = readdir($handle))) {

            if ($file != "." && $file != "..") {

                // IF IT"S A FILE THEN DELETE IT
                if(is_file($path."/".$file)) {

                    if(unlink($path."/".$file)) {
                    $debugStr .= "Deleted File: ".$file."<br />";   
                    }

                } else {

                    // IT IS A DIRECTORY
                    // CRAWL THROUGH THE DIRECTORY AND DELETE IT'S CONTENTS

                    if($handle2 = opendir($path."/".$file)) {

                        while (false !== ($file2 = readdir($handle2))) {

                            if ($file2 != "." && $file2 != "..") {
                                if(unlink($path."/".$file."/".$file2)) {
                                $debugStr .= "Deleted File: $file/$file2<br />";    
                                }
                            }

                        }

                    }

                    if(rmdir($path."/".$file)) {
                    $debugStr .= "Directory: ".$file."<br />";  
                    }

                }

            }

        }

    }
    echo $debugStr;
}

<?php

delete_directory($dirname) {
   if (is_dir($dirname))
      $dir_handle = opendir($dirname);
   if (!$dir_handle)
      return false;
   while($file = readdir($dir_handle)) {
      if ($file != "." && $file != "..") {
         if (!is_dir($dirname."/".$file))
            unlink($dirname."/".$file);
         else
            delete_directory($dirname.'/'.$file);    
      }
   }
   closedir($dir_handle);
   rmdir($dirname);
   return true;
 }
?>

如果您使用的是5.1及以上版本,

<?php
function deleteDir($dir) {
   $iterator = new RecursiveDirectoryIterator($dir);
   foreach (new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::CHILD_FIRST) as $file) 
   {
      if ($file->isDir()) {
         rmdir($file->getPathname());
      } else {
         unlink($file->getPathname());
      }
   }
   rmdir($dir);
}

deleteDir("temporary");
?>
