Question

Ok so i’m having a bit of an issue with nl2br() and str_replace.

I have a field in my database which is being echoed out. It is added into the database by the user with a textarea in a form.

When it echos out (if the user has added a line) I get \r\n echoing out too.

I tried using nl2b and str_replace, but it still doesnt work. I used str_replace for other items within the same echo, which works fine, but it refuses to work specifically for the \r\n

Here’s what I have tried so far:

echo str_replace("\r\n", "", $message->message);

and

echo nl2br($message->message);

Neither work. I can’t figure it out!

Answer 1

It looks as CI escaped \r\n too. so if you want your regular linebreaks back try it like this

$a = " hello \\r\\n world";
echo $a;
// hello \r\n world

Now the replace

$b = preg_replace('~\\\r\\\n~',"<br>", $a);
echo $b;
// hello <br> world

Or

$c = preg_replace('~\\\r\\\n~',"\n", $a);
echo $c;
/*
 hello 
 world
*/
