PHPExcel 是用来操作Office Excel 文档的一个PHP类库，它基于微软的OpenXML标准和PHP语言。可以使用它来读取、写入不同格式的电子表格，如 Excel (BIFF) .xls, Excel 2007 (OfficeOpenXML) .xlsx, CSV, Libre/OpenOffice Calc .ods, Gnumeric, PDF, HTML等等。 要求： PHP 5.2.0 版本及以上 PHP extension php_zip 开启 (如果你需要使用 PHPExcel 来操作 .xlsx .ods or .gnumeric 文件) PHP extension php_xml 开启 PHP extension php_gd2 开启(选填, 如果需要计算准确的列宽需要开启此扩展)
