　　　　_rmdir($compile,1);
　}
// 列出文件和目录
function _scandir($dir) {
    if(function_exists('scandir')) return scandir($dir);   // 有些服务器禁用了scandir
    $dh = opendir($dir);
    $arr = array();
    while($file = readdir($dh)) {
        if($file == '.' || $file == '..') continue;
        $arr[] = $file;
    }
    closedir($dh);
    return $arr;
}
// 递归删除目录
function _rmdir($dir, $keepdir = 0) {
    if(!is_dir($dir) || $dir == '/' || $dir == '../') return FALSE;    // 避免意外删除整站数据
    $files = _scandir($dir);
    foreach($files as $file) {
        if($file == '.' || $file == '..') continue;
        $filepath = $dir.'/'.$file;
        if(!is_dir($filepath)) {
            try{unlink($filepath);}catch(Exception $e){}
        }else{
            _rmdir($filepath);
