slashes problem!

Jag får ett konstigt fel med följande script. Stripslashes verkar inte arbeta alls. (') blir (///'). Varför tre slashes?

<?
/*-----------------------------------------------------------------------

require("../database.inc.php3");

if (isset($save)) {
//Setting from form. Settings to db.

$subject = addslashes($subject); 
$from = addslashes($from); 
$letter = addslashes($letter); 


$sql_update = "update n_settings set subject = '$subject', letterfrom = '$from', letter = '$letter'";
mysql_query($sql_update)
	or die(mysql_error());

} else {
//Settings from db.

$sql_query = "select \* from n_settings";
$retid = mysql_query($sql_query)
	or die(mysql_error());
$row = mysql_fetch_array($retid);

$subject = stripslashes($row\["subject"\]);
$from = stripslashes($row\["letterfrom"\]); 
$letter = stripslashes($row\["letter"\]); 

}

require("../header.inc.php3");
?>

<span class="clsheadline2">Settings</span><br>
<span class="clstext">Use this form to make a template for your letters.</span>

<br><br>

<form action="newsletter_settings.php3" method="post">

</form>
