PHP导出excel文件的几种方式

先说说动态生成的内容当作文件来下载的方法:

1、通过把Content-Type设置为application/octet-stream,可以把动态生成的内容当作文件来下载;

2、用Content-Disposition设置下载的文件名;

3、 基本上,下载程序都是这么写的:

<?php
$filename = "document.txt";
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $filename);
print "Hello!";
?>

4、当然要考虑到浏览器兼容性和对如果文件名是中文的话出现异常bug,我们这么写:

<?php
$ua = $_SERVER["HTTP_USER_AGENT"];
$filename = "文件名.txt";
$encoded_filename = urlencode($filename);
$encoded_filename = str_replace("+", "%20", $encoded_filename);
header('Content-Type: application/octet-stream');
if (preg_match("/MSIE/", $ua)) {
header('Content-Disposition: attachment; filename="' . $encoded_filename . '"');
} else if (preg_match("/Firefox/", $ua)) {
header('Content-Disposition: attachment; filename*="utf8\'\'' . $filename . '"');
} else {
header('Content-Disposition: attachment; filename="' . $filename . '"');
}
print 'ABC';
?>

导出excel文件

1、原始方式:发送header,用附件的表头发送到用户浏览器表示是要下载的,然后读出数据库中的数据,一条一条的解析,写入excel格式的文件中。

    $mysql_server_name = 'localhost'; //改成自己的mysql数据库服务器

    $mysql_username = 'admin'; //改成自己的mysql数据库用户名

    $mysql_password = 'p1234567'; //改成自己的mysql数据库密码

    $mysql_database = 'tp6demo'; //改成自己的mysql数据库名

    $conn=@mysqli_connect($mysql_server_name,$mysql_username,$mysql_password,$mysql_database); //连接数据库

    //连接数据库错误提示

    if (mysqli_connect_errno($conn)) {

        die("连接 MySQL 失败: " . mysqli_connect_error());

    }

    mysqli_query($conn,"set names gbk"); //数据库编码格式

    // mysqli_set_charset($conn,"utf8");//设置默认客户端字符集。

    // mysqli_select_db($conn,$mysql_database); //更改连接的默认数据库

    $file_type = "vnd.ms-excel";
    $file_ending = "xls";
    $savename = date('Y-m-d');
    header("Content-Type: application/$file_type;charset=utf8");
    header("Content-Disposition: attachment; filename=".$savename.".$file_ending");
    $sep = "\t";
    //查询代码
    //SELECT `tel`  FROM `users` WHERE `data` < 20201203 GROUP BY `tel` ORDER BY `users`.`data`  DESC LIMIT 100
    $sql = "SELECT `username`,`email`  FROM `tp_user` GROUP BY `username` LIMIT 12";

    $query = mysqli_query($conn,$sql);

    $content .= 'username'.$sep.'email'."\r";

    while($row = mysqli_fetch_array($query)){

        $content .=  $row['username'].$sep.$row['email']."\r";

    }

    // 释放结果集+关闭MySQL数据库连接

    @mysqli_free_result($result);

    @mysqli_close($conn);

    exit($content);
