通过 PHP 导出为 CSV [英] Export to CSV via PHP

问题描述

假设我有一个数据库....有没有办法通过 PHP 将数据库中的内容导出到 CSV 文件(和文本文件 [如果可能])?

Let's say I have a database.... is there a way I can export what I have from the database to a CSV file (and text file [if possible]) via PHP?

推荐答案

我个人使用此功能从任何数组创建 CSV 内容.

I personally use this function to create CSV content from any array.

function array2csv(array &$array)
{
   if (count($array) == 0) {
     return null;
   }
   ob_start();
   $df = fopen("php://output", 'w');
   fputcsv($df, array_keys(reset($array)));
   foreach ($array as $row) {
      fputcsv($df, $row);
   }
   fclose($df);
   return ob_get_clean();
}

然后您可以让您的用户使用以下内容下载该文件:

Then you can make your user download that file using something like:

function download_send_headers($filename) {
    // disable caching
    $now = gmdate("D, d M Y H:i:s");
    header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
    header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
    header("Last-Modified: {$now} GMT");

    // force download  
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");

    // disposition / encoding on response body
    header("Content-Disposition: attachment;filename={$filename}");
    header("Content-Transfer-Encoding: binary");
}

使用示例:

download_send_headers("data_export_" . date("Y-m-d") . ".csv");
echo array2csv($array);
die();
