Writing a string array to text file separated by new line character

Question

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:

Answer 1

Try this:

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

Answer 2

You can simply write it back using implode:

file_put_contents('file.csv', implode(PHP_EOL, $data));

Answer 3

If you want to add new lines, then why are you first removing them?

$data = explode("\n", $_GET['TxtareaInput']);

Keep only this line:

fwrite($ourFileHandle, $data);

It will write your data to the file as it was received.

If you want to replace all new lines by carriage returns before writing to file, use this code:

    fwrite($ourFileHandle, str_replace("\n", "\r", $data));
