在Excel中导出数据，然后使用PHP从Excel导入。 DB是MySQL
– 我有一些表格，我想用excel格式导出。 这一步相当于用户inputsearch条件，所有匹配的行将被导出到Excel文件中。
– 用户对excel文件进行更改。 添加或更新行。
– 用户上传文件，所有更新的行在数据库中得到更新，所有添加的行被添加到数据库中。
所有这一切，我想在PHP和它使用的数据库是MySQL。 服务器正在运行Linux（没有COM！）
我有导出和导入部分，我上面解释了单独做。
我正在使用PHPExcelReader读取文件并保存。 但是，这需要用户先下载模板，从导出的Excel中复制数据并将其粘贴到模板中。
对于导出，我只是创build一个简单的HTML表，愚弄浏览器，它是一个Excel！ Excel会在保存该文件的同时打开HTML表格，但当然，它会改变格式并使之成为有效的Excel文件。
请提出一些想法，我怎样才能使它工作？ ：/
谢谢…我非常感谢你的帮助。
