输出到Excel，如何定义不同的列

Question

我正在将数据从数据库输出到 Excel（必须是 .xls 格式），但如何告诉 Excel 将数据放入新单元格或开始新行？

/** Set the headers */
header('Content-type: application/vnd.ms-excel');
header('Content-disposition: attachment;filename=referrals.xls');

/** Output the column headers (We don't need the ID, so drop it) */
foreach($referrals[0] as $key => $value) :
    $array_keys[$key] = $key;
endforeach;
unset($array_keys['ID']);
echo join('???', $array_keys).'New row???';

/** Output the data */
foreach($referrals as $referral) : foreach($referral as $key => $value) :
        $referral_array[$key] = $value;
    endforeach;
    unset($referral_array['ID']);
    echo join('???', $referral_array).'New row???';
endforeach;

Answer 1

尝试 \t 和 \n，就像

echo join("\t", $array_keys)."\n";

\t 代表新列，\n 代表新行
