如何在PHP中递归删除目录及其全部内容（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rmdir手册页中的第一个注释？

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

Answer 2

对于* nix中您可以使用rm -R为Windows shell_exec或DEL /S folder_name。

Answer 3

大厦The Pixel Developer's comment，采用SPL一个片段可能会是这样的：

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

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

rmdir($dir); 

^{注：它确实没有健全检查，并利用在PHP 5.3.0与FilesystemIterator推出SKIP_DOTS标志。当然，$todo可以是if/else。重要的一点是，CHILD_FIRST用于在其父（文件夹）之前首先迭代子文件（文件）。}

Answer 4

是这样的吗？

function delete_folder($folder) { 
    $glob = glob($folder); 
    foreach ($glob as $g) { 
     if (!is_dir($g)) { 
      unlink($g); 
     } else { 
      delete_folder("$g/*"); 
      rmdir($g); 
     } 
    } 
} 

Answer 5

“简单”的代码工作，并且可以通过一个十岁阅读：

function deleteNonEmptyDir($dir) 
{ 
    if (is_dir($dir)) 
    { 
     $objects = scandir($dir); 

     foreach ($objects as $object) 
     { 
      if ($object != "." && $object != "..") 
      { 
       if (filetype($dir . "/" . $object) == "dir") 
       { 
        deleteNonEmptyDir($dir . "/" . $object); 
       } 
       else 
       { 
        unlink($dir . "/" . $object); 
       } 
      } 
     } 

     reset($objects); 
     rmdir($dir); 
    } 
} 

请注意，我所做的就是扩展/简化和修复（非空的没有工作dir）解决方案： In PHP how do I recursively remove all folders that aren't empty?

Answer 6

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); 
}

还有更多的例子在这里另一个线程： A recursive remove directory function for PHP?

如果您正在使用Yii，那么你可以将它留给框架：

CFileHelper::removeDirectory($my_directory); 

Answer 8

我中庸之道使这个代码，从一些StackOverflow讨论。我还没有在Linux环境下测试。这是为了删除一个文件或目录制作，完全：

function splRm(SplFileInfo $i) 
{ 
    $path = $i->getRealPath(); 

    if ($i->isDir()) { 
     echo 'D - ' . $path . '<br />'; 
     rmdir($path); 
    } elseif($i->isFile()) { 
     echo 'F - ' . $path . '<br />'; 
     unlink($path); 
    } 
} 

function splRrm(SplFileInfo $j) 
{ 
    $path = $j->getRealPath(); 

    if ($j->isDir()) { 
     $rdi = new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS); 
     $rii = new RecursiveIteratorIterator($rdi, RecursiveIteratorIterator::CHILD_FIRST); 
     foreach ($rii as $i) { 
      splRm($i); 
     } 
    } 
    splRm($j); 

} 

splRrm(new SplFileInfo(__DIR__.'/../dirOrFileName'));

     return rmdir($dirname);

    reset($objects); 
    rmdir($dirname); 

    return !is_dir($dirname);

Answer 10

例与glob()功能。它将递归删除所有文件和文件夹，包括以点开头的文件。

delete_all('folder'); 

function delete_all($item) { 
    if (is_dir($item)) { 
     array_map('delete_all', array_diff(glob("$item/{,.}*", GLOB_BRACE), array("$item/.", "$item/.."))); 
     rmdir($item); 
    } else { 
     unlink($item); 
    } 
};

改性的@XzaR溶液变体。它会删除空文件夹，当所有文件都从中删除时，它会抛出异常而不是返回错误。

function recursivelyRemoveDirectory($source, $removeOnlyChildren = true) 
{ 
    if (empty($source) || file_exists($source) === false) { 
     throw new Exception("File does not exist: '$source'"); 
    } 

    if (is_file($source) || is_link($source)) { 
     if (false === unlink($source)) { 
      throw new Exception("Cannot delete file '$source'"); 
     } 
    } 

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

    foreach ($files as $fileInfo) { 
     /** @var SplFileInfo $fileInfo */ 
     if ($fileInfo->isDir()) { 
      if ($this->recursivelyRemoveDirectory($fileInfo->getRealPath()) === false) { 
       throw new Exception("Failed to remove directory '{$fileInfo->getRealPath()}'"); 
      } 
      if (false === rmdir($fileInfo->getRealPath())) { 
       throw new Exception("Failed to remove empty directory '{$fileInfo->getRealPath()}'"); 
      } 
     } else { 
      if (unlink($fileInfo->getRealPath()) === false) { 
       throw new Exception("Failed to remove file '{$fileInfo->getRealPath()}'"); 
      } 
     } 
    } 

    if ($removeOnlyChildren === false) { 
     if (false === rmdir($source)) { 
      throw new Exception("Cannot remove directory '$source'"); 
     } 
    } 
}

增强@Artefacto的溶液 - 校正输入错误和简化的代码，对于两个工作 - 空& &非空目录。

function recursive_rmdir($dir) { 
    if(is_dir($dir)) { 
     $objects = array_diff(scandir($dir), array('..', '.')); 
     foreach ($objects as $object) { 
     $objectPath = $dir."/".$object; 
     if(is_dir($objectPath)) 
      recursive_rmdir($objectPath); 
     else 
      unlink($objectPath); 
     } 
     rmdir($dir); 
    } 
    } 

Answer 14

unlinkr功能递归确保它不会删除脚本本身删除指定路径的所有文件夹和文件。

function unlinkr($dir, $pattern = "*") { 
    // find all files and folders matching pattern 
    $files = glob($dir . "/$pattern"); 

    //interate thorugh the files and folders 
    foreach($files as $file){ 
    //if it is a directory then re-call unlinkr function to delete files inside this directory  
     if (is_dir($file) and !in_array($file, array('..', '.'))) { 
      echo "<p>opening directory $file </p>"; 
      unlinkr($file, $pattern); 
      //remove the directory itself 
      echo "<p> deleting directory $file </p>"; 
      rmdir($file); 
     } else if(is_file($file) and ($file != __FILE__)) { 
      // make sure you don't delete the current script 
      echo "<p>deleting file $file </p>"; 
      unlink($file); 
     } 
    } 
} 

，如果你想删除，你把这个脚本中的所有文件和文件夹，然后将其称为以下

//get current working directory 
$dir = getcwd(); 
unlinkr($dir); 

，如果你只想删除只是PHP文件，然后把它作为以下

unlinkr($dir, "*.php"); 

你可以使用任何其他路径删除的文件，以及

unlinkr("/home/user/temp"); 

这将删除home/user/temp目录中的所有文件。

我使用此代码...

function rmDirectory($dir) { 
     foreach(glob($dir . '/*') as $file) { 
      if(is_dir($file)) 
       rrmdir($file); 
      else 
       unlink($file); 
     } 
     rmdir($dir); 
    } 

或这一个...

<?php 
public static function delTree($dir) { 
    $files = array_diff(scandir($dir), array('.','..')); 
    foreach ($files as $file) { 
     (is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file"); 
    } 
    return rmdir($dir); 
    } 
?>

function deltree_cat($folder) 
{ 
    if (is_dir($folder)) 
    { 
      $handle = opendir($folder); 
      while ($subfile = readdir($handle)) 
      { 
        if ($subfile == '.' or $subfile == '..') continue; 
        if (is_file($subfile)) unlink("{$folder}/{$subfile}"); 
        else deltree_cat("{$folder}/{$subfile}"); 
      } 
      closedir($handle); 
      rmdir ($folder); 
    } 
    else 
    { 
     unlink($folder); 
    } 
}

一旦您完成运行测试，只是删除＃从#unlink和#rmdir在课堂上。

<?php 
class RMRFiles { 

     function __construct(){ 
     } 

    public function recScan($mainDir, $allData = array()) 
    { 

    // hide files 
    $hidefiles = array(
    ".", 
    "..") ; 

    //start reading directory 
    $dirContent = scandir($mainDir) ; 

     //cycle through 
     foreach ($dirContent as $key => $content) 
     { 
      $path = $mainDir . '/' . $content ; 

      // if is readable/file 
      if (! in_array($content, $hidefiles)) 
      { 
      if (is_file($path) && is_readable($path)) 
      { 
      #delete files within directory 
      #unlink($path); 
      $allData['unlink'][] = $path ; 
      } 

      // if is readable/directory 
      else 
      if (is_dir($path) && is_readable($path)) 
      { 
      /*recursive*/ 
      $allData = $this->recScan($path, $allData) ; 

      #finally remove directory 
      $allData['rmdir'][]=$path; 
      #rmdir($path); 
      } 
      } 
     } 

    return $allData ;
