SLASHING A POST ARRAY

Try this little chunk of code to do two things : (1) Slash an entire array, and (2) Create variables from your form's field names on your POST page.

foreach ($_POST as $key => $val) {
    $$key = addslashes($val);
}

Now, for example, if you have a field named "firstname" on your form and you post to the PHP processing page, this script will create a variable named "$firstname" in which you can use throughout the rest of the script. Saves some time, and it also slashes user input to reduce the risk of SQL injection.
