如何在PHP中遞歸刪除目錄及其全部內容（文件+子目錄）？

Question

如何在PHP中刪除目錄及其全部內容（文件和子目錄）？

Answer 1

您是否嘗試過rmdir手冊頁中的第一個註釋？

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

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

Answer 3

大廈The Pixel Developer's comment，採用SPL一個片段可能會是這樣的：

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

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

rmdir($dir); 

^{注：它確實沒有健全檢查，並利用在PHP 5.3.0與FilesystemIterator推出SKIP_DOTS標誌。當然，$todo可以是if/else。重要的一點是，CHILD_FIRST用於在其父（文件夾）之前首先迭代子文件（文件）。}

Answer 4

是這樣的嗎？

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

「簡單」的代碼工作，並且可以通過一個十歲閱讀：

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); 
    } 
} 

請注意，我所做的就是擴展/簡化和修復（非空的沒有工作dir）解決方案： In PHP how do I recursively remove all folders that aren't empty?

Answer 6

刪除路徑中的所有文件和文件夾。

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 7

還有更多的例子在這裏另一個線程： A recursive remove directory function for PHP?

如果您正在使用Yii，那麼你可以將它留給框架：

CFileHelper::removeDirectory($my_directory); 

Answer 8

我中庸之道使這個代碼，從一些StackOverflow討論。我還沒有在Linux環境下測試。這是爲了刪除一個文件或目錄製作，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'));

function rmdir_recursive($dirname) { 

    /**

     foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dirname, FilesystemIterator::SKIP_DOTS), RecursiveIteratorIterator::CHILD_FIRST) as $path) { 
      $path->isDir() ? rmdir($path->getPathname()) : unlink($path->getRealPath()); 
     } 

     return rmdir($dirname); 

    } 

    /**

       continue; 
      } 
      $path->isDir() ? rmdir($path->getPathname()) : unlink($path->getRealPath()); 
     } 

     return rmdir($dirname); 

    } 

    /**

    if (!is_dir($dirname)) {

    $objects = scandir($dirname); 

    foreach ($objects as $object) {

     } 
     filetype($dirname . DIRECTORY_SEPARATOR . $object) === 'dir' ? rmdir_recursive($dirname . DIRECTORY_SEPARATOR . $object) : unlink($dirname . DIRECTORY_SEPARATOR . $object); 
    } 

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

    return !is_dir($dirname); 

} 

Answer 10

例與glob()功能。它將遞歸刪除所有文件和文件夾，包括以點開頭的文件。

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溶液變體。它會刪除空文件夾，當所有文件都從中刪除時，它會拋出異常而不是返回錯誤。

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'"); 
     } 
    } 
}

增強@Artefacto的溶液 - 校正輸入錯誤和簡化的代碼，對於兩個工作 - 空& &非空目錄。

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功能遞歸確保它不會刪除腳本本身刪除指定路徑的所有文件夾和文件。

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); 
     } 
    } 
} 

，如果你想刪除，你把這個腳本中的所有文件和文件夾，然後將其稱爲以下

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

，如果你只想刪除只是PHP文件，然後把它作爲以下

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

你可以使用任何其他路徑刪除的文件，以及

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

這將刪除home/user/temp目錄中的所有文件。

我使用此代碼...

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

或這一個...

<?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); 
    } 
?> 

Answer 16

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); 
    } 
}

一旦您完成運行測試，只是刪除＃從#unlink和#rmdir在課堂上。

<?php

    // 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 ;
