优化版:

function read_dir_all($dir) {
$ret = array();
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if($file != ‘.’ && $file !== ‘..’) {
$cur_path = $dir . DIRECTORY_SEPARATOR . $file;
if(is_dir($cur_path)) {
$ret[$cur_path] = read_dir_all($cur_path);
} else {
$ret[$cur_path] = $cur_path;
}
}
}
closedir($handle);
}
return $ret;
}
