php - 如何将所有 $row 变量写入文本文件
问题描述
我有以下代码，并想使用 file_put_contents(); 将所有 $row 变量写入文本文件；我尝试执行以下操作，但它不起作用。我不确定我是否将它错误地放在大括号内：我正在尝试从一些视频中学习，但找不到任何有关如何插入查询的视频...

$h = fopen('invoice_level1monthly.txt', 'a');
fwrite($h, $invoice);
fclose($h);
由于某种原因，$row 变量没有通过，我必须使用其他变量，例如 $price_level1monthly，但最新信息未附加到文件中，如图所示：
在此处输入图像描述
上面应该有两张图片
$path = getcwd()."/invoice/invoice_level1monthly.$_SESSION['u_uid']";
