Double(")/Single Quote(') Problem

[chchar]

Hello,

How to enable user to enter single quote and double
quote into 1 text field and then save it into table ?

Eg. Let take the example of the following PHP program.
When user enter double quote into item description field, I may
facing a problem to insert because of double quote.

<!-- ### Start Of program -->
<form>
Item Desc : <input type=text name=desc>
<input type=submit name=button>
</form>

<?
if ($button)
{
..........
$sql="insert into my_tbl values (\"$desc\") ";
$dbh=mysql_query("$sql");
........
}
?>
<!-- ### End Of program -->
