删除文件夹中的所有文件 到“分离”,水珠(" $目录/ * . * ")); 删除文件夹中所有。*-文件(不带"."和"..") 到“分离”,array_diff(水珠(“目录/美元。*),数组(“目录/美元。”,“目录/美元. .”))) 现在删除文件夹本身 删除文件夹(目录)

这里有一个简单的解决办法

$dirname = $_POST['d'];
    $folder_handler = dir($dirname);
    while ($file = $folder_handler->read()) {
        if ($file == "." || $file == "..")
            continue;
        unlink($dirname.'/'.$file);

    }
   $folder_handler->close();
   rmdir($dirname);

如果你不确定，给定的路径是目录或文件，那么你可以使用这个函数删除路径

function deletePath($path) {
        if(is_file($path)){
            unlink($path);
        } elseif(is_dir($path)){
            $path = (substr($path, -1) !== DIRECTORY_SEPARATOR) ? $path . DIRECTORY_SEPARATOR : $path;
            $files = glob($path . '*');
            foreach ($files as $file) {
                deleteDirPath($file);
            }
            rmdir($path);
        } else {
            return false;
        }
}

现在至少有两种选择。

Before deleting the folder, delete all its files and folders (and this means recursion!). Here is an example: public static function deleteDir($dirPath) { if (! is_dir($dirPath)) { throw new InvalidArgumentException("$dirPath must be a directory"); } if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') { $dirPath .= '/'; } $files = glob($dirPath . '*', GLOB_MARK); foreach ($files as $file) { if (is_dir($file)) { self::deleteDir($file); } else { unlink($file); } } rmdir($dirPath); } And if you are using 5.2+ you can use a RecursiveIterator to do it without implementing the recursion yourself: $dir = 'samples' . DIRECTORY_SEPARATOR . 'sampledirtree'; $it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS); $files = new RecursiveIteratorIterator($it, RecursiveIteratorIterator::CHILD_FIRST); foreach($files as $file) { if ($file->isDir()){ rmdir($file->getRealPath()); } else { unlink($file->getRealPath()); } } rmdir($dir);

$directory (string) -递归删除。

$options (array) -用于删除目录。 有效的选项是: traverseSymlinks:布尔值，是否也应该遍历指向目录的符号链接。默认为false，这意味着符号链接目录的内容不会被删除。在这种默认情况下，只会删除符号链接。

public static function removeDirectory($directory,$options=array())
{
    if(!isset($options['traverseSymlinks']))
        $options['traverseSymlinks']=false;
    $items=glob($directory.DIRECTORY_SEPARATOR.'{,.}*',GLOB_MARK | GLOB_BRACE);
    foreach($items as $item)
    {
        if(basename($item)=='.' || basename($item)=='..')
            continue;
        if(substr($item,-1)==DIRECTORY_SEPARATOR)
        {
            if(!$options['traverseSymlinks'] && is_link(rtrim($item,DIRECTORY_SEPARATOR)))
                unlink(rtrim($item,DIRECTORY_SEPARATOR));
            else
                self::removeDirectory($item,$options);
        }
        else
            unlink($item);
    }
    if(is_dir($directory=rtrim($directory,'\\/')))
    {
        if(is_link($directory))
            unlink($directory);
        else
            rmdir($directory);
    }
}

这里有一个完美的解决方案:

function unlink_r($from) {
    if (!file_exists($from)) {return false;}
    $dir = opendir($from);
    while (false !== ($file = readdir($dir))) {
        if ($file == '.' OR $file == '..') {continue;}

        if (is_dir($from . DIRECTORY_SEPARATOR . $file)) {
            unlink_r($from . DIRECTORY_SEPARATOR . $file);
        }
        else {
            unlink($from . DIRECTORY_SEPARATOR . $file);
        }
    }
    rmdir($from);
    closedir($dir);
    return true;
}
