It looks like you using regular expression. How about this one

echo implode(preg_split('/\r?\n/', $s), '<br>');

What you're trying to do can be done using implode, explode, and str_replace. The latter should replace any \r characters (seeing as they're optional). You then can explode the string using \n as delimiter, and implode it again using <br>. But that would mean calling 3 functions, which is a bit redundant considering there is a single function that does exactly what you need: nl2br

return implode(
    '<br/>',
    //split on \n
    explode(
        "\n",
       //remove any \r chars
        str_replace(
            "\r",
            '',
            $s
        )
    )
);
//The results are the same as this clean, simple one-liner
return nl2br($s);

Tl;tr

use nl2br, it's as simple as that, and it'll do exactly what you want, with the least amount of effort required.

I'd do:

return implode("<br />", explode("\R", $s));

Where \R stands for any line break, \n or \r or \r\n

You can write like this :

return implode("<br />", explode("\r\n", s));
