PHP操作excel的一个例子

<?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);

?>
