It is the best to use PHP_EOL. It's cross-platform and will automatically choose the correct newline character[s] for the platform PHP is running on.

$txt = "Goofy".PHP_EOL;

\r\n

add the carriage return in front.

if you want write \n in file use from file_put_contents[$File_Handle,$Text_For_Write,FILE_APPEND]

I'm trying to write username and password to a new line in a txt file. The output should be something like this in the txt file. I know this is not very secure but its just for learning purposes

Sebastian   password
John        hfsjaijn

This is what i have so far

if[isset[$_GET['register']]] //  
{
    $user  = $_GET['username'];
    $password=$_GET['password'];
    $fh = fopen["file.txt","a+"];
    fwrite[$fh,$user."\n"]; //write to txtfile
    fwrite[$fh,$password."\n"]; // write to txtfile
    fclose[$fh];
}

EDIT: Here's the solution for me:

if [isset[$_POST['register']]] {
   $user  = $_POST['username'];
   $password = $_POST['password'].PHP_EOL;
   $fh = fopen["file.txt","a+"];
   fwrite[$fh,$user." ".$password]; //write to txtfile
  
   fclose[$fh];
}

Use PHP_EOL which produces \r\n or \n

$data = 'my data' . PHP_EOL . 'my data';
$fp = fopen['my_file', 'a'];
fwrite[$fp, $data];
fclose[$fp];

// File output

my data
my data

You append a newline to both the username and the password, i.e. the output would be something like

Sebastian
password
John
hfsjaijn

use fwrite[$fh,$user." ".$password."\n"]; instead to have them both on one line.
Or use fputcsv[] to write the data and fgetcsv[] to fetch it. This way you would at least avoid encoding problems like e.g. with $username='Charles, III';

...i.e. setting aside all the things that are wrong about storing plain passwords in plain files and using _GET for this type of operation [use _POST instead] ;-]

fwrite[$handle, "
"."\r\n"];

Add this under

$password = $_POST['password'].PHP_EOL;

this. .

How about you store it like this? Maybe in username:password format, so

sebastion:password123
anotheruser:password321

Then you can use list[$username,$password] = explode[':',file_get_contents['users.txt']]; to parse the data on your end.
