当列的值为0时，CSV使用PHP删除一行数据

$file = fopen('data.csv', 'r');
$data = array();

while (($row = fgetcsv($file)) !== false) {
    $data[] = $row;
}

fclose($file);

foreach ($data as $key => $row) {
    if ($row[0] == 0) {
        unset($data[$key]);
    }
}

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

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

fclose($file);
