Weird str_replace behavior

[NYSiRacer]

$first = "blah blah blah\n ha ha ha";
$second = str_replace("\n","<br>",$first);
/*
Why does it produce:
[color=blue]blah blah blah
<br> ha ha ha[/color]
in a plain text file, and not:
[color=blue]blah blah blah<br> ha ha ha[/color]
?
[COLOR=darkblue]Shouldn't it replace [b]\n[/b] with [b]<br>[/b] instead of adding a [b]<br>[/b] after [b]\n[/b]?[/COLOR]
Or should I just use preg_replace instead...
*/

Thanks.

Ah, fork it all.

string = preg_replace("/\r\n|\n\r|\n|\r/", "<br/>", $string);

So \r\n works, not \n...
Weird, I recall, Windows uses \r\n as line breaks, while Linux uses \n as line breaks. I have a Linux server, how come I need to use \r\n? Any clue?

Thanks.

Linux is capable of binaries as well.

Your file has been seperated into \r\n by whatever wrote it.

Was it generated on a Windows system?

[NYSiRacer]

No, it was generated on a RedHat Linux, from a textarea.

have u tried using nl2br ? :/

[NYSiRacer]

No, I haven't, it works now by using \r\n, I was just wondering why it'd do that on a Linux...
