How to literally print \n in string using php

Question

I need to literally print \n inside of the the this.value.split

$rows .= "<textarea onkeyup='this.rows = (this.value.split(\"\n\").length||1);' ...

I cut the code short so its easier to read.

PHP parses it as a new line. How can I rewrite this string so that it will actually print \n ??

Two ways:

echo "\\n"; //escape it

echo '\n'; //use single quotes

You need to backslash your backslash:

\\n

Alternatively, you could use single quotes to delimit your string, but this would mean you would have to escape all the literal single quotes.

Booo 5 seconds before me just bc I had to add a second part :-P

still printing blank. try it! try echoing out a textarea with that js function included

wait this is working.. i feel like something else in my code is removing the new line odd

it works when i simplify it at least. i will accept this answer when it becomes available

@Neal You snooze you lose :P
