nl2br function and double spaces?

[Matthew Sims]

Hey all,

So I started using nl2br and love it. But when I convert back from
<br> to \n, it produces double spaces instead of single space.

Converting \n to <br>:
$emailBody=nl2b r($_POST["emailBody"]);
$emailBody=str_ replace("<br />", "<br>", "$emailBody ");

Converting <br> to \n:
$edit["emailBody"]=str_replace("< br>","\n",$edi t["emailBody"]);

Now what was once single new lines is now doubled.

Any ideas?

nl2br() converts "\n" to "<br />\n".
You then remove the "<br />", but the "\n" remains, and then you add another.

You are correct.

Shortly after I posted this message, I figured it out.

$emailBody=str_ replace("\n", "<br>", $_POST["emailBody"]);
$emailBody=str_ replace("<br>", "\n", $_POST["emailBody"]);

Don't use nl2br! :)

Better still, in my opinion, is to only convert the original when preparing
for html presentation and don't store it in the original variable. Leave the
original alone. Why convert back and forth when you don't have to?
