How to strip_tags from mysql insert values

How would I go about stripping tags (and slashes) from mysql insert values in the provided example?

Is this a satisfactory security measure to prevent an injection attack?

Thanks!
$sql="INSERT INTO contact (fname, lname, email, phone, address1, address2, title, company, referrer, list, message)
		VALUES
		('$_POST[fname]','$_POST[lname]','$_POST[email]','$_POST[phone]','$_POST[address1]','$_POST[address2]','$_POST[title]','$_POST[company]','$_POST[referrer]','$_POST[list]','$_POST[message]')";

This should work:

$sql="INSERT INTO contact (fname, lname, email, phone, address1, address2, title, company, referrer, list, message)
VALUES('" . strip_tags($_POST[fname]) . "','" . strip_tags($_POST[lname]) . "','" . strip_tags($_POST[email]) ."','" . strip_tags($_POST[phone]) ."','" . strip_tags($_POST[address1]) . "','" . strip_tags($_POST[address2]) . "','" . strip_tags($_POST[title]) . "','" . strip_tags($_POST[company]) . "','" . strip_tags($_POST[referrer]) . "','" . strip_tags($_POST[list]) . "','" . strip_tags($_POST[message]) . "')";

Cheers

Works great, thanks! I had to single quote around list though - strip_tags($_POST['list']) for some reason it came off the rails otherwise. It's a radio button, so I guess it's a variable?? I've been (only) a front end guy for so long... some of this mystifies me.

Thanks again!

Yes, sorry if if I didn't it but I had to go away urgently. list gives problem because it's a php function name so you have to enclose in quotes or use something like 'mylist'.

I'm glad to helped you. Thank you for points.
