使用php将mysql查询导出为可下载的.csv文件 [英] Using php to export a mysql query to a downloadable .csv file

问题描述

我已经尝试了我的判断，以避免提出这个问题（我在论坛上已经看过并尝试了大量的例子），大部分工作让我相信我错过了一些事情。我有一个链接设置将我的表导出为可下载的.csv文件。当我单击链接代码以csv格式转储表时，BUT而不是作为附件加载，它只显示html中的表的内容。

I've tried my darnest to avoid asking this question (I viewed and try a ton of examples already on the forum), most partially work which leads me to believe I'm missing something. I have a link setup to export my table into a downloadable .csv file. When I click the link the code dumps the table in csv format, BUT instead of it loading as an attachment it just displays the contents of the table in html.

<?php

include('bikes.php');    //db connection settings
if ($_GET['action'] == 'download')
{
header('Content-Disposition: attachment; filename="downloaded.csv"');

$query = "SELECT * FROM bikes";

$export = mysql_query ($query ) or die ( "Sql error : " . mysql_error( ) );

$fields = mysql_num_fields ( $export );

for ( $i = 0; $i < $fields; $i++ )
{
    $header .= mysql_field_name( $export , $i ) . "\t";
}

while( $row = mysql_fetch_row( $export ) )
{
    $line = '';
    foreach( $row as $value )
    {                                            
        if ( ( !isset( $value ) ) || ( $value == "" ) )
        {
            $value = "\t";
        }
        else
        {
            $value = str_replace( '"' , '""' , $value );
            $value = '"' . $value . '"' . "\t";
        }
        $line .= $value;
    }
    $data .= trim( $line ) . "\n";
}
$data = str_replace( "\r" , "" , $data );

if ( $data == "" )
{
    $data = "\n(0) Records Found!\n";                        
}

print "$header\n$data";

}
exit();

php?>

我的结果如何

A，B，C，D，A ，B，C，D - 我不知道为什么当我点击我的链接（download.php？action = download），这不是提示我将文件保存到我的硬盘驱动器，而不是只显示在

A, B, C, D, A, B, C, D -- I have no idea why when I click my link (download.php?action=download) that is does not prompt me to save the file to my hard drive, instead of just displaying the information on the page.

任何帮助将非常感谢！

推荐答案

使用在发送输出之前：

header('Content-Disposition: attachment; filename="downloaded.csv"');
