php导出mysql到excel乱码的解决办法：首先设置时区以及head头信息；然后通过“ob_end_clean();”清除缓冲区；接着设置表格信息；最后查询内容导出数据库数据即可。

PHP查询数据库导出excel并且解决乱码问题，原生代码无需插件

近日写一个信息系统，需要把数据库的内容导出到excel

下面把我的贴出我的代码，不需要phpexcel插件

系统要求：php5.6+

<?php
date_default_timezone_set('PRC');//设置时区
 
/*设置head头信息*/
ob_end_clean();//清除缓冲区,避免乱码
Header("Content-Type:application/vnd.ms-excel;charset=UTF-8");
Header("Accept-Ranges:bytes");
Header("Content-Disposition:attachment;filename="."导出excel的名字".date('YmdHis').".xls");
Header("Pragma:no-cache");
Header("Expires:0");
 
$str = $str2 = null;
/*设置表格信息*/
$str.= "序号"."\\t";
$str.= "学号"."\\t";
$str.= "姓名"."\\t";
$str.= "性别"."\\t";
$str.= "学院"."\\t";
$str.= "年级"."\\t";
$str.= "班级"."\\t";
$str.= "手机号"."\\t";
$str.= "报名时间"."\\t\\r\\n";
$info = iconv("UTF-8","GBK",$str);
echo $info;
 
/*查询内容导出数据库数据*/
$con = new mysqli("localhost", "root", "password", "detabase");
if (!$con) {
    die(mysqli_error()) ;
}
//$sql = " select * from bmxx";
//$res = mysqli_query($con, $sql);
 
mysqli_query($con,"SET NAMES utf8");//解决数据库中有汉字时显示在前台出现乱码问题
$result = mysqli_query($con,"SELECT * FROM `bmxx`");
 
while($row = mysqli_fetch_assoc($result)){
    $list[] = $row;
}
mysqli_free_result($result);
mysqli_close($con);
$co = 1;
foreach($list as $v){
    $str2.= trim($co++)."\\t";
    $str2.= trim(iconv("UTF-8","GBK","\\t".$v['num']."\\t"))."\\t";
    $str2.= trim(iconv("UTF-8","GBK",$v['name']))."\\t";
    $str2.= trim(iconv("UTF-8","GBK",$v['sex']))."\\t";
    $str2.= trim(iconv("UTF-8","GBK",$v['xueyuan']))."\\t";
    $str2.= trim(iconv("UTF-8","GBK",$v['grade']))."\\t";
    $str2.= trim(iconv("UTF-8","GBK",$v['class']))."\\t";
    $str2.= trim(iconv("UTF-8","GBK",$v['phone']))."\\t";
    $str2.= trim(iconv("UTF-8","GBK",$v['time']))."\\t\\r\\n";
}
echo $str2;
?>

一开始没有加这行代码，导致输出乱码。在每次生成数据之前，清除一下缓冲区就好了、

ob_end_clean();//清除缓冲区,避免乱码
