dedecms织梦后台增加php导出到excel功能不出现乱码代码实例

在后台目录创建一个php文件toexcel.php,在最上面加入代码；

require_once(dirname(__FILE__).'/config.php');
require_once(DEDEINC.'/typelink.class.php');
require_once(DEDEINC.'/datalistcp.class.php');
require_once(DEDEADMIN.'/inc/inc_list_functions.php');

加入导出到excel类；

class Excel
{
private $head;
private $body;
public function addHeader($arr){
foreach($arr as $headVal){
$headVal = $this->charset($headVal);
$this->head .= "{$headVal}\t ";
}
$this->head .= "\n";
}
public function addBody($arr){
foreach($arr as $arrBody){
foreach($arrBody as $bodyVal){
$bodyVal = $this->charset($bodyVal);
$this->body .= "{$bodyVal}\t ";
}
$this->body .= "\n";
}
}
public function downLoad($filename=''){
if(!$filename)
$filename = date('YmdHis',time()).'.xls';
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:attachment;filename=$filename");
header("Content-Type:charset=gb2312");
if($this->head)
echo $this->head;
echo $this->body;
}
public function charset($string){
return mb_convert_encoding($string,'GBK','auto');
}
}

代码解释：
1.输出列名数组，并转码

public function addHeader($arr){
foreach($arr as $headVal){
$headVal = $this->charset($headVal);
$this->head .= "{$headVal}\t ";
}
$this->head .= "\n";
}

2.输出导出内容数组，并转码

public function addBody($arr){
foreach($arr as $arrBody){
foreach($arrBody as $bodyVal){
$bodyVal = $this->charset($bodyVal);
$this->body .= "{$bodyVal}\t ";
}
$this->body .= "\n";
}
}

3.设置header头部信息和导出到excel内容，并输出到浏览器

public function downLoad($filename=''){
if(!$filename)
$filename = date('YmdHis',time()).'.xls';
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:attachment;filename=$filename");
header("Content-Type:charset=gb2312");
if($this->head)
echo $this->head;
echo $this->body;
}

4.转码，这里不用iconv函数，有可能会与gd冲突导致输出空白。用

public function charset($string){
return mb_convert_encoding($string,'GBK','auto');
}

7.调用方法；

$excel = new Excel();
$excel->addHeader(array('列一','列二','列三','列四'));
global $dsql;
$sql="select 列一字段,列二字段,列三字段,列四字段 from 表名";
$dsql->SetQuery($sql);
$dsql->Execute();
while($row = $dsql->GetArray()){
$list[]=$row;
}
unset($row);
$excel->addBody($list);
$excel->downLoad();

后天添加导出到excel代码：
找到后台目录下的templets目录，下面有个content_list.htm文件，
找到

<a href="javascript:;" onClick="cAtts('attsDel',event,this)" class="coolbg">删除属性</a>

在后面加一段代码

<?php if($channelid==1) echo " <a href=\"toexcel.php\" class=\"coolbg\" target=\"_blank\">导出到excel</a>\r\n"; ?>

$channelid就是你的模型id，根据你导出的表填写。填写完之后打开后台栏目列表就出现导出按钮
