Question

I have this code

if($hgroup['groupid'] == $row_groups['groupid']){
  $problem++;
  $hostname=DBfetch($cursor_gethost_again);
  $replace_macro=array('/{HOSTNAME}/','/{HOST.NAME}/');
  $problem_text=$problem_text.$trigger['description'];
  $problem_text=preg_replace($replace_macro,$hostname['name'],$problem_text);
  $problem_text=$problem_text."\r\n";
}

It is a code generating in cycle. Can anybody help me how to make that stupid newline? I have to do it this way because I’m modifying one code. So I want to keep that layout.
It doesn’t work. It will print it with text. I also try preg_replace to <br />.

If you’re trying to print out HTML, the new line is not using \r\n but by appending <br/>.

In a comment you confirmed that you were trying to view this in a browser. As Kolink said, browsers collapse whitespaces to a space, so you lose your new line information.

If you were to output the value to a standard output, like the console, then \r\n are the solution. Same thing if you are dealing with a file you want to write to.

If you wanted to output it both to a standard output AND then in HTML, I’d suggest first filling it with \r\n, output your variable, then use str_replace (documentation here) to convert all your \r\n to <br/>:

$html_problem_text = str_replace('\r\n', '<br/>', $problem_text);
