ascii squares or what?

PHPslide

Hey everyone I am having a wierd issue that I think may be causing problems.

I have a form (one text area box) submiting data to a text file (int_update.txt).

In the code I change any line breaks /n to so that it can simply be included somewhere all set with html etc.

The problem is in the int_update.txt file I am getting what looks like [] (pretent "[]" is a square and not two brackets. I don't know how to make that square)

Heres the code for writing to the file if its of any consequence:

# STRIP SLASHES BEFORE TEXT GOES TO FILE
$update = stripslashes($update);

# MAKE LINE BREAKS INTO HTML LINE BREAKS BEFOR MAKING TEXT FILE
$update = str_replace("\n","<br>",$update);

# CREATE FILE WITH UPDATE TEXT IN IT
$creTextFile = fopen("int_update.txt","w") or die("Could not open or create int_update.txt file");
fwrite($creTextFile,$update) or die("Could not write to int_update.txt file");
fclose($creTextFile)or die("Could not close the int_update.txt file");

Actually the only reason I ask is because when I print the success message it renders two 's as one . And I think maybe these squares are the reason? I can view source and see two 's and still when its echoed it will be like tehre is only one in internet explorer.

OK I guess that square is a non-printable ASCII character, how and why is it there? anyone know anything? Much appreciated!

The network standard for line enders, supposedly followed by Web browsers and SMTP mailers, is CR-LF, not the Unix LF. The odd nonprintable character you are seeing probably an unstripped CR.

$update = str_replace('\r\n', ' ', $update);

Thanks for responding. You are right. I happen to get it done and before I seen your reply but I do it in two steps. Maybe I can do it on one how you listed. Thanks much.

$update = str_replace("\r", '', $update);
$update = str_replace("\n", "<br>", $update);
