PHP瀏覽器導出csv格式文件

解釋幾個請求頭：

• Content-type：內容類型
• Content-Disposition：設置爲瀏覽器顯示（Disposition）或作爲文件下載（attachment）
• Expires：設置瀏覽器緩存有效期，0爲不緩存
• Cache-Control：設置請求和響應的緩存機制指令，指令均爲單向，must-revalidate表示每次使用緩存前校驗有效期，post-check=0,pre-check=0是IE5.0纔有的防cache聲明
• Content-Transfer-Encoding：內容傳輸編碼
• Pragma：HTTP1.0客戶端向後兼容，與 Cache-Control: no-cache 作用相同

<?php

function exportCsv($data, $title, $filename = '報表')
{
    foreach ($title as $k => $v) {
        $title[$k] = iconv("UTF-8", "GBK//IGNORE", $v);
    }

    $csv_data = '';
    $csv_data .= implode(',', $title) . PHP_EOL;
    foreach ($data as $k => $v) {
        foreach ($v as $i => $item) {
            $v[$i] = iconv("UTF-8", "GBK//IGNORE", $item);
        }
        $csv_data .= implode(',', $v) . PHP_EOL;
    }

    header('Content-type:csv');
    header('Content-Disposition: attachment; filename=' . $filename . '.csv');
    header("Content-Transfer-Encoding: binary");
    header('Expires: 0');
    if (strpos($_SERVER['HTTP_USER_AGENT'], "MSIE") !== FALSE)
    {
        header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
        header('Pragma: no-cache');
    }
    else
    {
        header('Cache-Control: no-store, max-age=0, no-cache');
        header('Pragma: no-cache');
    }
    echo $csv_data;
}

$title = [
    '第一列',
    '第二列',
    '第三列',
];
$data = [
    [1, 2, 3],
    [1, 2, 3],
    [1, 2, 3],
];
exportCsv($data, $title, '報表');
