Don't use $_REQUEST, but $_POST instead. $_REQUEST is usually littered
with extra variables as you've noticed. $_POST and $_GET I think should
be better.
One thing you could do is put all the form fields in the same array:
<form method="post" action="">
<input type="text" name="my_cvs[field1]" />
<input type="text" name="my_cvs[field2]" />
<input type="text" name="my_cvs[field3]" />
....
<input type="text" name="my_cvs[fieldN]" />
<input type="submit" name="submit">
</form>
And then use $_POST['my_cvs'] instead of the entire $_POST, that way you
can be sure you get only the fields you wanted.
