phpexcelreader读取excel自动生成表和字段
这个主要是采用phpexcelreader的功能实现，根据excel的文件名和excel第一行生成表名及字段，数据从第二行开始依次导入。



phpexcelreader下载地址 ： http://sourceforge.net/projects/phpexcelreader/

下载下来有个 “phpExcelReader.zip”的压缩包。解压，我们需要的只有 Excel 文件夹的内容，首先把 “oleread.inc” 改为 “oleread.inc.php”

修改“reader.php”文件

修改第31行  require_once 'Spreadsheet/Excel/Reader/OLERead.php';
改为 ”   ：     require_once 'oleread.inc.php';
                 第 261行 =&  改为 =  号就 OK 了

源码及示例文件，以及流程都在下载文件里！
本人php新手，错误之处还请谅解。

上传文件页面！
