strings from db to php to js

[Arcadian]

OK,

to preserve carriage returns /line feeds in this scenario:

INPUT:

textarea (with carriage returns/line feeds) written to mySQL (field type = text)

OUTPUT: (reverse)

mySQL (text) to php variable to javascript variable into textarea PRESERVING carriage returns/line feeds?

HELP!

I can think of a weird way: to parse the php string using n12br() and then again translating it into the resulting HTML breaks into "\r\n" but there must be a better way. heck i dont know if this even works.

You mean you want the HTML file to be:

var js = "something\r\n";

?

Then this works

$str = preg_replace('/\r\n/', '\r\n', $str);

excellent!

I suppose I need to be wary of whether or not the original text comes from Mac/UNIX/PC?

I just realized that you don't need regular expressions for this, so you could have just used str_replace instead of preg_replace.

Anyway, if you separate the function into 2 functions, so that you have one to replace \r and another one to replace \n, then you don't need if statements to worry about Mac/Win/Unix.
