PHP向sql表添加2d数组和1d数组的问题

好的，我现在遇到的问题是，我不明白如何使用

exec（）函数将数据传递到
LOAD data LOCAL infle
SQL命令

在我的代码的第57行，我尝试使用
内爆（'，'，$row）
。我也尝试过使用
serialize（$row）
，首先我尝试过引用，就像下面的两行一样，我也尝试过手动给它每个参数和值，这是可行的，但不实用，因为导入的CSV文件中每行上都会有100多个条目，一定有更好的方法可以做到这一点，如果有人能告诉我怎么做，我很高兴

问题发生在以下代码的第57行：

你能试试下面的方法吗

    $query = "LOAD DATA LOCAL INFILE ".$database->quote($row)." INTO TABLE `$eT`
              FIELDS TERMINATED BY ".$database->quote($fieldSeparator)."
              LINES TERMINATED BY ".$database->quote($lineSeparator));


$affectedRows = $database->exec($query);

但是要检查查询，请尝试
die（$query）在执行之前，打印查询并查看有什么问题
