PHP实现文件下载功能，提示压缩包损坏及打不开的解决方法

// 文件下载 public static function downFile($id,$admin_id,$cid,$type) { $company = checkAdminCompany($admin_id,$cid);         if (!$company) {             return [                 'status' => -4,                 'statusMsg' => '公司不存在'             ];         }         if ($type=='file') {         // 判断是否有权限下载文件 $checkFileRole = self::checkFileRole($admin_id,$cid,$id); if (!$checkFileRole) { return [ 'status' => 777, 'statusMsg' => '没有操作权限' ]; }         $select_sql = "SELECT * FROM cloud_storage WHERE id in ($id)"; send_execute_sql($select_sql,$fileInfo);         } elseif ($type == 'list') {         // 判断是否有权限移动目录下的文件 $checkRole = self::checkRole($admin_id,$cid,$id); if (!$checkRole) { return [ 'status' => '777', 'statusMsg' => '没有操作权限' ]; }         $select_sql = "SELECT * FROM cloud_storage WHERE list_id = $id"; send_execute_sql($select_sql,$fileInfo);         } if (empty($fileInfo)) {         return [ 'status' => -400, 'statusMsg' => '文件不存在' ];         }           foreach ($fileInfo as $key => $value) { $paths[$key] = $fileInfo[$key]['path']; }         //这里需要注意该目录是否存在，并且有创建的权限 $filename = 'logs/down/test.zip';  if(!file_exists($filename)){ $zip = new ZipArchive(); if ($zip->open($filename, ZipArchive::CREATE)==TRUE) { foreach( $paths as $val){   if(file_exists($val)){    $zip->addFile( $val, basename($val));   }  }  $zip->close(); } } if(!file_exists($filename)){ exit("无法找到文件"); } header("Cache-Control: public"); header("Content-Description: File Transfer"); header('Content-disposition: attachment; filename='.basename($filename)); //文件名 header("Content-Type: application/zip"); //zip格式的 header("Content-Transfer-Encoding: binary"); //告诉浏览器，这是二进制文件 header('Content-Length: '. filesize($filename)); //告诉浏览器，文件大小 ob_clean(); flush(); @readfile($filename); unlink($fileurl);    exit; }

其实大多数的错误都是在缺少

ob_clean(); flush();
