如何在PHP中递归删除目录及其全部内容(文件+子目录)?

您试过手册第页的第一个注释吗? rmdir ?

 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); 
   } 
 }

建立在 The Pixel Developer's comment ,使用SPL的代码段可能如下所示:

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

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

rmdir($dir);

^{注:确实如此 不 健全性检查并使用php 5.3.0中的文件系统迭代器引入的skip_dots标志。当然, $todo 可以是一个 if / else . 重要的是 CHILD_FIRST 用于在子级(文件)的父级(文件夹)之前对其进行迭代。}

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);
}

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

这里还有另一个包含更多示例的线程: A recursive remove directory function for PHP?

如果您使用的是yii,那么您可以将其留在框架中:

CFileHelper::removeDirectory($my_directory);

<?php

use RecursiveDirectoryIterator;
use RecursiveIteratorIterator;
use SplFileInfo;

/**

function rrmdir($source, $removeOnlyChildren = false)
{
    if(empty($source) || file_exists($source) === false)
    {
        return false;
    }

    if(is_file($source) || is_link($source))
    {
        return unlink($source);
    }

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

    //$fileinfo as SplFileInfo
    foreach($files as $fileinfo)
    {
        if($fileinfo->isDir())
        {
            if(rrmdir($fileinfo->getRealPath()) === false)
            {
                return false;
            }
        }
        else
        {
            if(unlink($fileinfo->getRealPath()) === false)
            {
                return false;
            }
        }
    }

    if($removeOnlyChildren === false)
    {
        return rmdir($source);
    }

    return true;
}

“简单”代码,10岁的孩子可以阅读:

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,我所做的只是扩展/简化和修复(不适用于非空目录)这里的解决方案: In PHP how do I recursively remove all folders that aren't empty?

增强了@artefactor的解决方案—更正了拼写错误和简化的代码,同时适用于空目录和非空目录。

  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); 
    } 
  }

像这样?

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

unlink函数通过确保不删除脚本本身,递归地删除给定路径中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); 
        }
    }
}

如果要删除放置此脚本的所有文件和文件夹,请按以下方式调用它

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

如果只想删除php文件,请按以下方式调用它

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

您也可以使用任何其他路径删除文件

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

这将删除home/user/temp目录中的所有文件。

一旦你完成了测试, 移除γ 从 未链接 和 γRMIDR 在班里。

<?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 ;

    }

100%工作溶液

public static function rmdir_recursive($directory, $delete_parent = null)
  {
    $files = glob($directory . '/{,.}[!.,!..]*',GLOB_MARK|GLOB_BRACE);
    foreach ($files as $file) {
      if (is_dir($file)) {
        self::rmdir_recursive($file, 1);
      } else {
        unlink($file);
      }
    }
    if ($delete_parent) {
      rmdir($directory);
    }
  }

似乎所有其他答案都假定给函数的路径总是一个目录。此变量用于删除目录和单个文件:

/**
 * Recursively delete a file or directory.  Use with care!
 *
 * @param string $path
 */
function recursiveRemove($path) {
    if (is_dir($path)) {
        foreach (scandir($path) as $entry) {
            if (!in_array($entry, ['.', '..'])) {
                recursiveRemove($path . DIRECTORY_SEPARATOR . $entry);
            }
        }
        rmdir($path);
    } else {
        unlink($path);
    }
}

我只是根据StackOverflow的讨论编写了这段代码。我还没有在Linux环境上测试。这样做是为了完全删除一个文件或目录:

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 ) {

    /**
     * FilesystemIterator and SKIP_DOTS
     */

    if ( class_exists( 'FilesystemIterator' ) && defined( 'FilesystemIterator::SKIP_DOTS' ) ) {

        if ( !is_dir( $dirname ) ) {
            return false;
        }

        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 );

    }

    /**
     * RecursiveDirectoryIterator and SKIP_DOTS
     */

    if ( class_exists( 'RecursiveDirectoryIterator' ) && defined( 'RecursiveDirectoryIterator::SKIP_DOTS' ) ) {

        if ( !is_dir( $dirname ) ) {
            return false;
        }

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

        return rmdir( $dirname );

    }

    /**
     * RecursiveIteratorIterator and RecursiveDirectoryIterator
     */

    if ( class_exists( 'RecursiveIteratorIterator' ) && class_exists( 'RecursiveDirectoryIterator' ) ) {

        if ( !is_dir( $dirname ) ) {
            return false;
        }

        foreach( new RecursiveIteratorIterator( new RecursiveDirectoryIterator( $dirname ), RecursiveIteratorIterator::CHILD_FIRST ) as $path ) {
            if ( in_array( $path->getFilename(), array( '.', '..' ) ) ) {
                continue;
            }
            $path->isDir() ? rmdir( $path->getPathname() ) : unlink( $path->getRealPath() );
        }

        return rmdir( $dirname );

    }

    /**
     * Scandir Recursive
     */

    if ( !is_dir( $dirname ) ) {
        return false;
    }

    $objects = scandir( $dirname );

    foreach ( $objects as $object ) {
        if ( $object === '.' || $object === '..' ) {
            continue;
        }
        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 );

}

实例与 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 );
    }
};

修改了@xzar解决方案的变体。当从文件夹中删除所有文件时,它会删除空文件夹,并抛出异常,而不是在出错时返回false。

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'");
        }
    }
}

我用这个代码…

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

或者这个…

<?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);
     }
}
