如何以递归方式删除PHP中的目录及其全部内容(文件+子目录)？

Question

如何在PHP中删除目录及其全部内容(文件和子目录)？

Answer 1

您是否尝试过手册页中的第一个注释rmdir？

 function rrmdir($dir) { 
   if (is_dir($dir)) { 
     $objects = scandir($dir); 
     foreach ($objects as $object) { 
       if ($object != "." && $object != "..") { 
         if (is_dir($dir."/".$object) && !is_link($dir."/".$object))
           rrmdir($dir."/".$object);
         else
           unlink($dir."/".$object); 
       } 
     }
     rmdir($dir); 
   } 
 }

Answer 2

在Pixel Developer的评论基础上,使用SPL的片段可能如下所示:

$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS),
    RecursiveIteratorIterator::CHILD_FIRST
);

foreach ($files as $fileinfo) {
    $todo = ($fileinfo->isDir() ? 'rmdir' : 'unlink');
    $todo($fileinfo->getRealPath());
}

rmdir($dir);

^{注意:它没有进行健全性检查,并使用PHP 5.3.0中的FilesystemIterator引入的SKIP_DOTS标志.当然,$todo可能是if/ else.重要的是,CHILD_FIRST它用于在父(文件夹)之前首先迭代子(文件).}

Answer 3

删除路径中的所有文件和文件夹.

function recurseRmdir($dir) {
  $files = array_diff(scandir($dir), array('.','..'));
  foreach ($files as $file) {
    (is_dir("$dir/$file")) ? recurseRmdir("$dir/$file") : unlink("$dir/$file");
  }
  return rmdir($dir);
}

Answer 4

对于*nix,您可以使用shell_execfor rm -R或DEL /S folder_namefor Windows.

Answer 5

还有另一个带有更多示例的线程: PHP的递归删除目录函数？

如果您使用Yii,那么您可以将其留在框架中:

CFileHelper::removeDirectory($my_directory);

<?php

use RecursiveDirectoryIterator;
use RecursiveIteratorIterator;
use SplFileInfo;
