PHP中导出Excel，将数据以Excel形式导出

现在，很多地方都需要导出数据，这里说一种简单的方法将数据以Excel的形式导出，方法如下：

<?php 
    date_default_timezone_set('PRC');//设置时区
    
    /*设置head头信息*/
    Header("Content-Type:application/vnd.ms-excel;charset=UTF-8");
    Header("Accept-Ranges:bytes");
    Header("Content-Disposition:attachment;filename=".date('YmdHis').".xls");
    Header("Pragma:no-cache");
    Header("Expires:0");
    
    $str = $str2 = null;
    /*设置表格信息*/
    $str.= "ID"."	";
    $str.= "用户名"."	";
    $str.= "密码"."	";
    $str.= "邮箱"."	
";
    $info = iconv("UTF-8","GBK",$str);
    echo $info;
    
    /*查询内容导出数据库数据*/
    $link = @mysql_connect('localhost','root','') or die('Failed to connect to the MySQL'); 
    mysql_select_db('l_test',$link);
    mysql_set_charset('utf8',$link);
    $query = 'select * from lt_user';
    $result = mysql_query($query);
    while($row = mysql_fetch_assoc($result)){
        $list[] = $row; 
    }
    mysql_free_result($result);
    mysql_close($link);
    
    foreach($list as $v){
        $str2.= trim(iconv("UTF-8","GBK",$v['id']))."	";
        $str2.= trim(iconv("UTF-8","GBK",$v['username']))."	";
        $str2.= trim(iconv("UTF-8","GBK",$v['passwd']))."	";
        $str2.= trim(iconv("UTF-8","GBK",$v['email']))."	
";
    }
    echo $str2;
?> 

这个方法相对简单，但在一些小的程序上，作为一个简单的方法还是不错的，希望能对大家有所帮助。
