When text string is mailed, extra line breaks are introducd

[Joshua Beall]

Hi all,

I have the following message string:

$message = <<<EOT
Personal Information:
Name: {$_POST["name"]}
Address: {$_POST["address"]}

EOT;

Now, when I echo this to the browser, (and view the source), it is exactly
what you would expect. Three lines of information. However, if I use
mail() or the PEAR Mail class to send $message via email, I get an extra
line break at the end of every line. What in the world would cause this?
Any ideas?

Try this instead:
$message = "Personal Information\n Name: {$_POST[name]}\n Address: {$_POST[address]}";

I'm betting on a few "\r" in the middle of the message being
converted to "\n".

That is the workaround that I have been using. I was just hoping there
another way.

Ah, of course, that would make perfect sense. I bet every line is getting
\r\n at the end of it when PHP stores the string. I suppose I could just do
a string replace to strip out all the \r characters. Oh well.

Thanks!

Removing all "\r"s might not be such a good idea ... some OS's use it as
the line break character. The ones I know of are:

Un*x \n
DOS/Win \r\n
Macintosh \r

Expecting only these and assuming the user will not type the character
with code zero, I do:

<?php
$input = $_POST['textarea'];
$input = str_replace("\r \n", "\x00", $input);
$input = str_replace("\r ", "\x00", $input);
$input = str_replace("\x 00", "\n", $input);
?>
