这就是这种情况。我有一个程序从数组中获取数据并将其显示在表格上。我创建了允许客户端输入新项目的文本输入类型，当单击提交按钮时，所有字段都将添加到表中。我在想是否有办法将数组写入文本文件并执行 fwrite 将客户端输入写入文本文件。我还注意到文本文件不断被覆盖，因此输入的数据不会保留，而不是
$handle=fopen($myfile, "w");
我应该使用
$handle=fopen($myfile, "a");
如果不存在文件，是否会修改工作，如果不存在，它将创建文本？
当我运行部分借用和创建的代码时，客户端新表不会添加到已经存在的表中。
抱歉，如果不清楚，我是新手。任何帮助将不胜感激，如果您需要更多信息，请告诉我。
这是我到目前为止开发的代码：
