str_replace problem

I'm having a problem getting str_replace to work properly in the following code:
Code: Select all
$un_comp = array(" ", "\n", ";}");
$comp = array("", "", "}");
$css = str_replace($un_comp, $comp, $_POST["css"]);
echo $css;
For some reason, it's not striping out the spaces or line breaks. What am I doing wrong?

Um, side note: you know you can't remove all the spaces, right?

Why not?

That aside, I can't duplicate the problem. Can you post an example of what isn't working?

For some reason, I never had much luck with str_replace on newlines. You might have better luck using preg_replace.

There are three versions of a "newline" combining two characters: \r (Mac), \n (Unix/Linux), and \r\n (Windows).

For new line, if it is not working, It might help.
Convert all the new line to break
Then replace <br /> to ""
