• 2 PHP used to have split and join functions, but they were deprecated as being aliases for the much wider used explode and implode functions. php/split – Elias Van Ootegem Commented Jan 13, 2015 at 12:17

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

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

PHP used to have split and join functions, but they were deprecated as being aliases for the much wider used explode and implode functions. RTM

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));
