Addslashes usage

I'm trying to use this upon its suggestion earlier on on this board, the syntax is

string addslashes(string str);

and the variable I'm using, I presume string (?) is $news, I was to allow ' to be used in the news, so I tried

$news addslashes($news "'");

and other varients on that, but they all
just generate a parse error!

Any help greatly appreciated with this.

Thanks

try
$news = addslashes($news);
and
$news = stripslashes($news);

THANK YOU!
Top work tried and worked, thanks, thats been driving me crazy for SO long!!!

A very happy tired James :-)
