php5 实现，两种方法：scandir和DirectoryIterator

function scan_all($dir){
    $temp = scandir($dir);
    if(is_array($temp) && count($temp)>2){
        array_shift($temp);
        array_shift($temp);
        foreach($temp as $v){
            $cur_dir=$dir.DIRECTORY_SEPARATOR.$v;
            if(is_dir($cur_dir)){
                echo $v." =>";
                echo "<blockquote>";
                scan_all($cur_dir);
                echo "</blockquote>";
            }else if(is_file($cur_dir)){
                echo "FILE:".$v."<br/>";
            }else{
                echo 'err';
            }
        }
    }
}
$dir = "D:/yourdir/";
scan_all($dir);

 

 

function directoryiterator($path)
{
$iterator = new DirectoryIterator($path);

foreach ($iterator as $fileinfo) {
if(!$fileinfo->isDot())
        {
if($fileinfo->isDir())
            {
echo $fileinfo.'=><blockquote>';
                directoryiterator($path.DIRECTORY_SEPARATOR.$fileinfo);
echo '</blockquote>';    
            }
else
            {
echo $fileinfo->getFilename().'<br/>';    
            }            
        }
    }
}
$dir = "D:/yourdir/";
directoryiterator($dir);
