PHP mail line break problem

问题:

I want to format content of the mail to show the content in different line. here is my message contetn. bu the \n and \r is not working in this case. it just shows all the content in one line.

$message = 'Thank you for using . We really appreciate your business.'."\r\n".'If you are making your payment by mail, please make the check out to "blah blah" and send it to:'."\n".'blah blah '."\n".'blah blah'."\n".'San Gabriel, CA 91776'."\n".'Please see the attached invoice in PDF format for easy saving & printing purposes.';

$attachment = chunk_split(base64_encode($pdfdoc));
$headers = "From: ".$from.$eol;
$headers .= "MIME-Version: 1.0".$eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol.$eol;
$headers .= "Content-Transfer-Encoding: 7bit".$eol;
$headers .= "This is a MIME encoded message.".$eol.$eol;
$headers .= "--".$separator.$eol;
$headers .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
$headers .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$headers .= $message.$eol.$eol;
$headers .= "--".$separator.$eol;
$headers .= "Content-Type: application/pdf; name=\"".$filename."\"".$eol;
$headers .= "Content-Transfer-Encoding: base64".$eol;
$headers .= "Content-Disposition: attachment".$eol.$eol;
$headers .= $attachment.$eol.$eol;
$headers .= "--".$separator."--";
mail($_POST['add6'],$subject, $message, $headers);

how can i do that?

回答1:

You're telling the email client the message is HTML, so the CR LF combination will be treated like any other whitespace.

To fix this, change the content type to show you are sending a plain text email

$headers .= "Content-Type: text/plain; charset=\"iso-8859-1\"".$eol;

Alternatively, turn your message into an HTML message - an easy way to do that in your case would be to run it through nl2br to turn the newlines into <br> tags

回答2:

Yep you've got Content-Type: text/html, so the CR LF is being treated like whitespace. Either send it as Content-Type: text/plain or call nl2br on your contents.

回答3:

Your content type is HTML so you should use br or p tags instead of line feeds

For \n to work it needs to be double quotes, not single. "\n" is the right thing, '\n' is wrong and will not work.
