嘿伙计们，我有我正在开发的这个 php 应用程序，我希望它能够正确地将数据导出到 excel 文档中，以便每个列标题都与该列中的所有数据一起导出。这是我到目前为止所拥有的，但它无法正常工作，因为所有列都显示在一行中。我怎样才能实现我想要的？有人请帮助我。这是当前的实现：

<?php require_once('connections/pgconn.php');


function cleanData(&$str)
{
$str = preg_replace("/\t/", "\\t", $str);
$str = preg_replace("/\r?\n/", "\\n", $str);
if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"';
}

// filename for download
$filename = "website_data_" . date('Ymd') . ".xls";

header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");

$flag = false;
$result = pg_query("SELECT to_char (a.CALLDATE,'yyyymm') as month,min(a.calldate) as      start_time,max(a.calldate) as end_time,
     ceil(SUM (a.CALLDURATION::integer) / 60) AS minutes,
     COUNT (DISTINCT a.IDENTIFIANT) AS distinct_callers,
a.zoneiddest as country_code,b.country
FROM cdr_data a,COUNTRY_CODES b
WHERE  a.CALLSUBCLASS = '002'
     AND  a.CALLCLASS = '008'
and a.zoneiddest::integer > 0
AND SUBSTR (a.CALLEDNUMBER, 1, 2) NOT IN
('77', '78', '75', '70', '71', '41', '31', '39', '76','79')

and not substr(a.zoneiddest , 1 ,3) in ('254','255','256','211','257','250','256')
and trim(a.zoneiddest)  = trim(b.country_code)
GROUP BY to_char (a.CALLDATE,'yyyymm') ,a.zoneiddest,b.country
ORDER BY 1") or die('Query failed!');

while(false !== ($row = pg_fetch_assoc($result))) {
if(!$flag) {
  // display field/column names as first row
  echo implode("\t", array_keys($row)) . "\r\n";
  $flag = true;
}
array_walk($row, 'cleanData');
echo implode("\t", array_values($row)) . "\r\n";
}
exit;
?>

我建议将您的查询导出为 CSV，告诉 PHP 创建一个 HTTP 响应为“ application/ms-excel ”内容类型，以便 IE 将自动启动 Excel，该 Excel 将在具有列名的列中导入 CSV：

$query = "COPY (SELECT .... ) TO '/path/reachable/with/php/file.csv' CSV;"

这样，您可以将 CSV 作为文件保存在服务器上，并在 PHP 中尽可能多地检索它。

$file = file_get_contents('/path/reachable/with/php/file.csv');
header('Content-Type: application/ms-excel');
echo $file;
