PHP newline character in Javascript, help!

[luckybird]

A PHP variable retrieved from DB with newline characters in it(obtained from user input textarea).
I want to echo it in Javascript.

However, it reports error which comes from the 'newline', cause it actually breaks the line in the output javascirpt code.

I tried to replace the 'newline', but it seems that it's NOT '\n', '\n\r' or '\r\n'

what should I do? :confused:

thanks!

Show the instruction with which you tried to remove the newline(s).

I used
str_replace('\n', '--', $str) // and, '\r', '\r\n', '\n\r'

The function nltobr() however, can locate the 'newline', correctly. But it doesn't remove it, just insert a <br> before it.

An alternative way might be trying to make the output of PHP varaible displayed in a single line by a certain way of encoding or sth. But I don't know how.

Any suggestions?

str_replace('\n', '--', $str) replaces 2 characters: the backslash and the r. In order to remove the newline you must put the to-be-replaced value within double quotes, because that interprets the \r correctly, i.e.
$str = str_replace("\n", '-', $str)

That's it! And that's why 'newline' cannot be escaped by addslashes(), because it's what it means, it's not characters like '\n', '\r'...

Thank you Ronald!
