html textarea --> php mail function produces additional line break

[Chris Schinzel]

Hi,

I'm reading text from a html textarea field (standard wrap
functionality, no value specified). If I display it via nl2br() (after
html form submission), everything's ok. But if I send it via mail() the
receiver gets each single line break (originating from textarea)
displayed by TWO line breaks. So the text needlessly gets inflated...
Can anybody help me out what to do to handle this problem?

Thanks in advance!

Regards,

Different clients will send line breaks differently:

un*x -- \n
mac -- \r
win -- \r\n
??? -- ???

So normalize input before anyhting else.

<?php
function normalize_lineb reaks($text) {
$text = str_replace("\r \n", "\n", $text); /* win -> un*x */
$text = str_replace("\r ", "\n", $text); /* mac -> un*x */
return $text;
}

mail($recipient , $subject, normalize_lineb reaks($_POST['text_area']));
?>

TEXT-ONLY mail to the whole "Reply-To:" address ("My Name" <my@address>)
may bypass my spam filter. If it does, I may reply from another address!
