Need help with Line Breaks, but in reverse...

[alexcmm]

Hello,

I'm hoping there's an easy way to turn a <BR> back into something else... preferrably a space. I'm using this code to turn a

/n

into a

<BR>

 

	$program=$_POST['program'];
$program = preg_replace("/\n/","\n<BR>\n",$program);

 

How can I do the reverse? Can you help?

[Psycho]

$program = preg_replace("\n<BR>\n","/\n/",$program);

Thanks mjdamato,

I am new, but I did think to try that before coming here and it doesn't work. Any more ideas?

I can see why that wouldn't work. "\n<BR>\n" isn't a valid regex as far as I'm aware.

 

You probably want this:

 

$program = preg_replace("/<BR>/","\n",$program);

 

Granted, I'm no regex master, but that should work.

First question. Why are you using....

 

preg_replace("/\n/","\n<BR>\n",$program);

 

when nl2br exists?

 

Take a look at the man entry for nl2br, I'm sure people have posted a reversal function.

You should be using the function nl2br() to add the <br /> tag before the newline characters "\n". Then to remove them and just leave the newline characters do a

<?php
$line = str_replace("<br />\n","\n",$line);
?>

Actually, <BR> is is being pulled from a file which I am including in my form, not an actual form field. I finally got it to work with this code:

$program=str_replace("<br>","\n", $program);

 

Thanks to all for your help!
