issue with \n\r and nl2br

Try:
$var = str_replace("\\\\r\\\\n","<br/>",$var);

this is how far I seem to get
index.php?p=separate\r\nlines

$var=$_GET[var];

what $var gets is "\\r\\n"   (don't understand why the change.   as I inputed "\r\n")

$unwanted=array("\r","\n","\r\n","\\r\\n","\\r\\n");
$wanted="<br/>";
$var= str_replace($unwanted,$wanted,$var);

results in $var = separate<br/>lines

when I put this in the text area it shows
separate<br/>lines

I wanted it to show
separate
lines

thanks for any help

If you want it on separate lines in a text area, you don't need to use <br/> - text areas pay attention to line breaks. Just change $wanted = "\r\n"; and you should see what you're looking for.

The problem is that by default, PHP tries to automatically escape special characters that are entered via the query string. It's a security thing, which you can turn off, but  that's not recommmended. It's better to simply fix any specific cases like this.

Hi gr8gonzo:
thanks for feedback
unfortunately your suggested didn't work

What does your code look like right now?

This is simple codes and should be working ...
NOTICE the way I use single quotes and double quotes in str_replace

$var = $_GET['p'];
$var = stripslashes($var);
// Turning \r\n to breakspace in textarea
echo '<textarea>'.str_replace('\r\n', "\r\n", $var).'</textarea>';

And here's for the learning purposes (for those who wonder) :-)

<?php

// \r\n on single quotes
$var1 = 'NO break \r\n space';
// \r\n on double quotes
$var2 = "YES break \r\n space";

// echo $var1 in TEXTAREA
echo 'Var#1: <textarea>'.$var1.'</textarea>';
// echo $var2 in TEXTAREA
echo 'Var#2: <textarea>'.$var2.'</textarea>';

?>
