Good to see this was resolved for after 's suggestion. The underlying issue is just line-ending handling: different platforms expect different end-of-line bytes, so using a portable constant removes the guesswork (see the PHP_EOL note on the PHP manual: PHP_EOL).

A compact, safer pattern is to build a single text line, sanitize inputs, append a platform-correct line ending, and write with an atomic append/lock. Example approach:

$line = sprintf(
  "First name: %s, Last name: %s, Email: %s%s",
  htmlspecialchars($_POST['fname']),
  htmlspecialchars($_POST['lname']),
  filter_var($_POST['email'], FILTER_SANITIZE_EMAIL),
  PHP_EOL
);

file_put_contents('data.txt', $line, FILE_APPEND | LOCK_EX);

See file_put_contents and htmlspecialchars for details.

Extra tips: if you keep using fopen/fwrite, always fclose and use locking (flock) to avoid race conditions. Use quoted array keys like $_POST['fname'] to avoid notices and to be compatible with newer PHP versions. When showing the saved file in a browser, convert newlines to HTML breaks or wrap the text in a preformatted block (or use nl2br). and also suggested workable alternatives — chr()/OS-specific endings and HTML breaks — but the PHP_EOL + atomic append approach is simplest and most portable.

Uhh don't you just hit the enter button?
And if you want them lined down on the actual web page that you are creating. You can just put <br> before the beginning of each line.

Try "\r\n" instead of just "\n" . \r is a carriage return.

Concetenate the statements like below with the single quotes.

fwrite($fh, 'Look, Ma,'.chr(13).' I wrote a file! ')

It works perfect!
