不囉嗦了，直接上代碼：
<?php
public function getxls($theDay){
//從數據庫去除數據(用的是cakePHP)
$act = TableRegistry::get('test');
$res = $act->getData($theDay);
//格式化
foreach($res as $value){
$con = array($value['username'],$value['shipdate'],$value['address'],$value['userphone'],$value['solution']);
$data[] = $con;
}
/*下載表格*/
if($data){
$output = "<HTML>";
$output .= "<HEAD>";
$output .= '<META http-equiv=Content-Type content="text/html; charset=utf8">';
$output .= "</HEAD>";
$output .= "<BODY>";
$output .= "<TABLE BORDER=1 width=100%>";
$output .= "<tr><td width=5%>ID</td><td width=6%>姓名</td><td width=8%>再配送日期</td><td width=12%>地址</td><td width=8%>電話</td><td width=13%>解決方案</td></tr>";
$i = 1;
if($data){
foreach ($data as $kvalue) {
$output .= "<tr><td>".$i++."</td><td>{$kvalue['0']}</td><td>{$kvalue['1']}</td><td>{$kvalue['2']}</td><td>{$kvalue['3']}</td><td>{$kvalue['4']}</td>";
}
}
$output .= "<tr><td> </td><td> </td><td> </td><td> </td><td> </td><td> </td><td> </td></tr>";
$output .= "</TABLE>";
$output .= "</BODY>";
$output .= "</HTML>";
$outname = '導出'.$theDay.'-售後表';
header("Content-type:application/msexcel"); //用php的header函數來聲明excel
header("Content-disposition: attachment; filename=".$outname.".xls"); //用php的header函數來聲明excel的格式

print($output); //下載excel文件到客戶端
exit;
