thinkphp删除Runtime缓存文件夹

 public function del_cache() {   header("Content-type: text/html; charset=utf-8");   //清文件缓存   $dirs = array('./Runtime/');   @mkdir('Runtime',0777,true);   //清理缓存   foreach($dirs as $value) {    $this->rmdirr($value);   }   $this->assign("jumpUrl","__ROOT__/");   $this->success('系统缓存清除成功！');   //echo '<div style="color:red;">系统缓存清除成功！</div>';     } 

/下面是处理方法

      public function rmdirr($dirname) {   if (!file_exists($dirname)) {    return false;   }   if (is_file($dirname) || is_link($dirname)) {    return unlink($dirname);   }   $dir = dir($dirname);   if($dir){    while (false !== $entry = $dir->read()) {     if ($entry == '.' || $entry == '..') {      continue;     }     //递归     $this->rmdirr($dirname . DIRECTORY_SEPARATOR . $entry);    }   }   $dir->close();   return rmdir($dirname);  }
