如何利用php导出excel数据表

利用php导出excel数据表代码

<?
Header("Content-type:application/octet-stream");
Header("Accept-Ranges:bytes");
Header("Content-type:application/vnd.ms-excel");  
Header("Content-Disposition:attachment;filename=test.xls");
$con = mysql_connect("localhost","数据库登陆名","数据库密码");
mysql_select_db("数据库名");
mysql_query('set names utf8');//数据库编码
$sql = "select 要输出的字段名，多个用逗号隔开 from 数据表单名";
$result = mysql_query($sql,$con);
echo "id/tusername";//输出的excel的列名，用/t换列
while ($rs=mysql_fetch_array($result)){
 echo "/n";//用/n换行
 echo $rs['输出字段名']."/t".$rs['输出字段名'];//用."/t".连接
}
?>

例子：

<?php
Header("Content-type:application/octet-stream");
Header("Accept-Ranges:bytes");
Header("Content-type:application/vnd.ms-excel");  
Header("Content-Disposition:attachment;filename=test.xls");
$con = mysql_connect("localhost","root","123456");
mysql_select_db("db_test");
mysql_query('set names utf8');
$sql = "select id,FirstName,LastName,Age,Hometown,Job from user";
$result = mysql_query($sql,$con);
echo "id/tFirstName/tLastName/tAge/tHometown/tJob";
while ($rs=mysql_fetch_array($result)){
 echo "/n";
 echo $rs['id']."/t".$rs['FirstName']."/t".$rs['LastName']."/t".$rs['Age']."/t".$rs['Hometown']."/t".$rs['Job'];
}
?>
