I'm creating files with the "file_put_contents" function of PHP, on my machine it opens normal on notepad ++, but when I send it to someone and it will open in ultra edit it asks "Do you want to convert 'file.txt' to DOS format? "
The function I'm using in a simple way
$dados = "Olá mundo!";
file_put_contents("arquivo.txt", $dados, FILE_APPEND);
How to solve it, I already looked at the web but did not see anything that I might be doing wrong.
Error screen:
