如何使用php在csv文件中写入2个数组

Question

我想在一个csv文件中写入2个数组并水平显示。

数组 1

Array
(
    [0] => Array
        (
            [0] => 501
            [1] => 8921
        )

    [1] => Array
        (
            [0] => 502
            [1] => 8446
        )
)

数组 2

Array
(
    [0] => Array
        (
            [0] => 501
            [1] => 8900
        )

    [1] => Array
        (
            [0] => 502
            [1] => 8436
        )
)

要写入 csv 文件的代码：

header("Content-type: text/csv; charset=utf-8; encoding=utf-8");
header("Content-Disposition: attachment; filename={$exportFileName}.csv");
header("Pragma: no-cache");
header("Expires: 0");

$file = fopen('php://output', 'w');
fputcsv($file, array('HID', 'WEEK1', 'HID', 'WEEK2')); 
foreach  ($fweek as $k=>$row) 
{
    fputcsv($file, $row);  // I want to include $sweek as well             
}

但目前，它只显示第一个数组。

任何提示/建议都会有很大帮助。提前致谢。

如果它们总是排成一行，您可以使用 foreach 的键到另一个数组并将它们合并。像这样：

foreach($fweek as $k => $row) {
    $row = array_merge($row, $sweek[$k]);
    fputcsv($file, $row);
}
