简单生成EXCEL

$arr_list = array(); //数据库读取, 获取要输出到EXCEL的数组

header('Content-type: application/vnd.ms-excel;');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Disposition: attachment; filename=activity.xls'); //filename:文件名
ob_start(); //打开缓存区
include 'file.html'; //输出内容到缓存区
$output = mb_convert_encoding(ob_get_clean(), 'GBK', 'UTF-8'); //缓存区取出，转换编码
echo $output; //输出




<?php
echo implode("t", array_keys($arr_list[0])),"n";
foreach($arr_list as $value){
 echo implode("t", $value),"n";
}
?>
