Question

我已经在该站点附近搜索了答案，但是找不到任何帮助我的问题。我有一个带有表单的脚本，我想在按下“提交”按钮时将输入的内容写到txt文件中（例如，在mytext.txt文件中逐行显示），或者可能仅是结果更简单。

结果/内容“ echo $ result ['text'];”应该保存到文本文件（mytext.txt）

我试图在每个“回声”之后添加类似的内容，但是它不起作用。这是示例代码。

$f = fopen("mytext.txt", "w");
fwrite($f,  $result);
fclose($f);

或

$f = fopen("mytext.txt", "w");
fwrite($f,  $username);
fclose($f);

或

$txt = "$result";
$myfile = file_put_contents('mytext.txt', $txt.PHP_EOL , FILE_APPEND | LOCK_EX);

但仍然没有运气。我该怎么做以及在哪里添加呢？使用PHP还是使用JavaScript？请帮助。

编辑：脚本的一部分（对不起，我忘了它）

Answer 1

如果在尝试运行此代码时遇到错误，请检查是否已授予PHP文件访问权限以将信息写入硬盘。

Answer 2

您必须检查要保存txt文件的目录是否可写。示例：

$contents = 'Here goes your content';
$dirName = __DIR__; //in case you're saving in another directory, you may use 'files/directory/' instead of __DIR__
$fileName = $dirName.'/mytext.txt';

if (!is_writable($dirName)) {
    throw new \Exception("This folder is not writable: '$dirName'");
}

//Checks if the content was added
if (!file_put_contents($fileName, $contents)) {
    throw new \Exception("Could not write to file: $fileName");
}

Answer 3

代码正确，可能是目录无权创建文件。

将结果保存到文本文件
