php壓縮文件失敗是因為缺少相關代碼語句，其解決辦法就是在代碼文件中添加“ob_clean();flush();”語句即可。

PHP實現文件下載功能，提示壓縮包損壞及打不開的解決方法

// 文件下載 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') {         // 判斷是否有權限下載文件 $checkFileRole = self::checkFileRole($admin_id,$cid,$id); if (!$checkFileRole) { return [ 'status' => 777, 'statusMsg' => '沒有操作權限' ]; }         $select_sql = "SELECT * FROM cloud_storage WHERE id in ($id)"; send_execute_sql($select_sql,$fileInfo);         } elseif ($type == 'list') {         // 判斷是否有權限移動目錄下的文件 $checkRole = self::checkRole($admin_id,$cid,$id); if (!$checkRole) { return [ 'status' => '777', 'statusMsg' => '沒有操作權限' ]; }         $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']; }         //這里需要注意該目錄是否存在，并且有創建的權限 $filename = 'logs/down/test.zip';  if(!file_exists($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("無法找到文件"); } header("Cache-Control: public"); header("Content-Description: File Transfer"); header('Content-disposition: attachment; filename='.basename($filename)); //文件名 header("Content-Type: application/zip"); //zip格式的 header("Content-Transfer-Encoding: binary"); //告訴瀏覽器，這是二進制文件 header('Content-Length: '. filesize($filename)); //告訴瀏覽器，文件大小 ob_clean(); flush(); @readfile($filename); unlink($fileurl);    exit; }

其實大多數的錯誤都是在缺少

ob_clean(); flush();
