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
