php匯出mysql到excel亂碼怎麼辦

php匯出mysql到excel亂碼的解決方法：先設定時區以及head頭資訊；然後透過「ob_end_clean();」清除緩衝區；接著設定表格資訊；最後查詢內容匯出資料庫資料即可。

PHP查詢資料庫匯出excel並且解決亂碼問題，原生程式碼不需要外掛程式

最近寫一個資訊系統，需要把資料庫的內容匯出到excel

下面把我的貼出我的程式碼，不需要phpphp外掛

系統需求：php5.6

<?php
date_default_timezone_set(&#39;PRC&#39;);//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(&#39;YmdHis&#39;).".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[&#39;num&#39;]."\t"))."\t";
    $str2.= trim(iconv("UTF-8","GBK",$v[&#39;name&#39;]))."\t";
    $str2.= trim(iconv("UTF-8","GBK",$v[&#39;sex&#39;]))."\t";
    $str2.= trim(iconv("UTF-8","GBK",$v[&#39;xueyuan&#39;]))."\t";
    $str2.= trim(iconv("UTF-8","GBK",$v[&#39;grade&#39;]))."\t";
    $str2.= trim(iconv("UTF-8","GBK",$v[&#39;class&#39;]))."\t";
    $str2.= trim(iconv("UTF-8","GBK",$v[&#39;phone&#39;]))."\t";
    $str2.= trim(iconv("UTF-8","GBK",$v[&#39;time&#39;]))."\t\r\n";
}
echo $str2;
?>

一開始沒有加上這行程式碼，導致輸出亂碼。在每次產生資料之前，清除緩衝區就好了、

ob_end_clean();//清除缓冲区,避免乱码
