- 我的表中有一些我想以excel格式導出的行。這一步相當於用戶輸入搜索條件，所有匹配的行將被導出到Excel文件中。在Excel中導出數據，然後使用PHP從Excel導入。數據庫是MySQL
- 用戶對excel文件進行更改。添加或更新行。
- 用戶上傳文件，所有更新的行在數據庫中得到更新，並且所有添加的行都被添加到數據庫中。
我想在PHP中做的所有事情以及它使用的數據庫是MySQL。服務器正在運行Linux（沒有COM！）
我有導出和導入部分，我上面單獨做了解釋。
我正在使用PHPExcelReader來讀取文件並保存它。但是，這要求用戶先下載模板，從導出的Excel中複製數據並將其粘貼到模板中。
對於導出，我只是創建一個簡單的HTML表，並愚弄瀏覽器，它是一個Excel！ Excel會在保存該文件的同時打開HTML表格，但當然，它將更改格式並使其有效Excel文件。
請問我該如何讓它工作一些想法？ ：/
謝謝......我非常感謝你的幫助。

最大的好處......它是一個用於編寫和讀取xls文件的單一庫，並且由於OP需要同時執行這兩個操作，因此這比單獨的不兼容庫用於讀取和寫入 – 2012-02-04 11:06:14
