Indent function

[WakeMeWithAKiss]

I have a function to clean up my html when using templates.

function indent($text,$n){
    if(is_string($text) && is_int($n)){
        $indent = "";
        $i = 0;
        while($i < $n){
            $i++;
            $indent.= "\t";
        }
        return str_replace("\n", "\n".$indent, str_replace(array("\r\n","\r"), "\n", $text));
    }
} 

Works perfect except when i have a textarea that has a load of line breaks in it and it adds 8 or so tabs in after each line break.
I'm really bad with this kinda of thing, is there any way someone could help me with a regex to stop it doing that to anything between "[no-indent]" and "[/no-indent]" ?

Thanks !
