在PHP中将CSV写入没有机箱的文件

$data = array(
    array('Name', 'Age', 'Gender'),
    array('John', 30, 'Male'),
    array('Sarah', 25, 'Female'),
    array('Mike', 40, 'Male')
);

$filename = 'output.csv';
$file = fopen($filename, 'w');

foreach ($data as $row) {
    fputcsv($file, $row);
}

fclose($file);

$data = array(
    array('Name', 'Age', 'Gender'),
    array('John', 30, 'Male'),
    array('Sarah', 25, 'Female'),
    array('Mike', 40, 'Male')
);

$folder = 'myfolder';
if (!file_exists($folder)) {
    mkdir($folder);
}

$filename = $folder . '/output.csv';
$file = fopen($filename, 'w');

foreach ($data as $row) {
    fputcsv($file, $row);
}

fclose($file);
