//$dir ->目录 $chmod->权限 如：755

function recurDir($dir,$chmod='') {
	if(is_dir($dir)) {
		if($handle = opendir($dir)) {
			while(false !== ($file = readdir($handle))) {

					if($file != '.' && $file != '..') {

						$chmod ? chmod($path,$chmod) : FALSE;
						echo $path.'<p>';
						recurDir($path);
					}
				}else{
					$path = $dir.'/'.$file;
					$chmod ? chmod($path,$chmod) : FALSE;
					echo $path.'<p>';
				}
			}
		}
		closedir($handle);
	}
}

recurDir($_SERVER['DOCUMENT_ROOT'],777);
