tmpfile and newlines

[totus]

Can someone explain how to get \n newlines into a tmpfile()?

Correction, I seem to be able to get them in there via fwrite but echoing them back shows all lines as one line after rewind.

hmm

Maybe I'd be better off sticking with creating a file and unlinking. Opinions??

\n should work.

Are you echoing them back in a browser? I.e., a browser that's trying to render it as HTML? I'm presuming you're not talking about Windows Notepad (which doesn't recognise linebreak characters as linebreaks) of course.

Thanks for the insight Weedpacket. I discovered the difference between \n and \r\n yesterday. My woes exist below, I don't think its a line break problem but more of a coding problem. The echo statement works fine, however, I'm not able to populate $mbody - email shows up with $mbody empty.

$programsn = tmpfile();

if (isset($HRA)) {
   fwrite($programsn, "Health Risk Assessment\n"); }

// email confirmation
$to = "[e-mail]";
$subject = "Hi!";
$hbody = file_get_contents('./includes/email-head.txt', true);
$fbody = file_get_contents('./includes/email-foot.txt', true);
fseek($programsn, 0);
echo fread($programsn, 1024);

$mbody = fread($programsn, 1024);
$body = $hbody . $mbody . $fbody;
mail($to, $subject, $body);

close($programsn);

echo fread($programsn, 1024);

$mbody = fread($programsn, 1024);

You fread() 1024 bytes of $programsn, and then you fread() another 1024 bytes of $programsn :o

$mbody = fread($progamsn, 1024);
echo $mbody;

Thank you Weedpacket for your eagle eyes 🙂
