It will cause an error. You have two options... well, just one really.
You could "escape" all quotation marks like this:
\"howdy howdy howdy\"
But I don't think most users will respond well to that. A better option is to use PHP's built-in function for dealing with this problem:
It's called "addslashes".
Use it like this:
$formcontents = addslashes($formcontents);
That way it will automatically escape the problemed text for you.
