Stripping all new lines

[Anon]

Can someone suggest some code to stripp all new line chars from a string?

The easiest way to do it is
$whatever = str_replace("\n","",$string_to_replace_new_lines_in);

Hmm it just doesnt work.

I have this:

$welcome = nl2br($welcome);
$welcome = str_replace("\n","",$welcome);

First, I thought that the nl2br would do the job but it doesnt. The str_replace still doesnt do the job I need.

Here is the scenario: The text here is entered in a user admin and displayed in a Flash text area. The nl characters actually display as new lines in the flash, even if they have no effect in a regular HTML doc. I can't figure out how to get them outta there.
