这是对于那些只喜欢简单处理一下excel朋友来说的
<?php
//定义一个excel文件
$workbook = "c:/my documents/test.xls";
$sheet = "sheet1";
//生成一个com对象$ex
$ex = new com("excel.sheet") or die ("连不上！！！");
//打开一个excel文件
$book = $ex->application->workbooks->open($workbook) or die ("打不开！！！");
$sheets = $book->worksheets($sheet);
$sheets->activate;
//获取一个单元格
$cell = $sheets->cells(5,5);
$cell->activate;
//给该单元格赋值
$cell->value = 999;
//保存为另一文件newtest.xls
$ex->application->activeworkbook->saveas("newtest.xls");
//关掉excel，如果想看效果，则注释掉下面两行，由用户手动关掉excel
$ex->application->activeworkbook->close("false");
unset ($ex);
?>
