2 questions about textbox editing

[B]#1[/B]ok im trying to make a wiki like thing. and i wanted to make it so it converts n’s to <br>
so i used the php str_replace(“n”, “<br>”, $source); and then fwrites it
but it doesn’t get rid of the n and when i set it equal to the javascript variable, “source”, it looks like

[code=html]var source=”text1
<br>text2
<br>”;[/code]

which results in a javascript error because it thinks its an unterminated string constant. how can i make it so I get rid of n when the page is saved.

[B]#2[/B] i also would like to know how to do the bold, italic, underline thing that is used to make posts lol. I know it has to do with document.selection(). i want it so i highlight it and press one of the 3, it puts the [B] & [/B] in the front and at the end of what i selected, and if nothing is selected it place [B][/B] wherever the text-type-dash-thing was left at. THanks!
