Writing a string array to text file separated by new line character
提问by Klone
I have a PHP page which accepts input from user in a text area. Multiple strings are accepted as input from user & would contain '\n' and I am scanning it as:
我有一个 PHP 页面，它接受用户在文本区域中的输入。多个字符串被接受为来自用户的输入 & 将包含 '\n' 并且我将其扫描为：
$data = explode("\n", $_GET['TxtareaInput']);
Each string should be moved into the text file with new line character separation. This is the code I am using now and it separates each string with a '^M' character:
每个字符串都应移动到带有换行符分隔的文本文件中。这是我现在使用的代码，它用 '^M' 字符分隔每个字符串：
foreach($data as $value){
fwrite($ourFileHandle, $value);
}
Is there anyway I can get each string followed by a carriage return?
无论如何我可以获得每个字符串后跟一个回车符？

Try this:
尝试这个：
$data = explode("\n", $_GET['TxtareaInput']);
foreach($data as $value){
fwrite($ourFileHandle, $value.PHP_EOL);
}

You can simply write it back using implode:
您可以简单地使用内爆将其写回：
file_put_contents('file.csv', implode(PHP_EOL, $data));

If you want to add new lines, then why are you first removing them?
如果要添加新行，为什么要先删除它们？
$data = explode("\n", $_GET['TxtareaInput']);
Keep only this line:
只保留这一行：
fwrite($ourFileHandle, $data);
It will write your data to the file as it was received.
它将在收到您的数据时将其写入文件。
If you want to replace all new lines by carriage returns before writing to file, use this code:
如果要在写入文件之前通过回车替换所有新行，请使用以下代码：
fwrite($ourFileHandle, str_replace("\n", "\r", $data));
