Hope some of the gurus around here can me stop feeling stupid.
Is there some way to have the same actions (like, say, STR_REPLACE(),
TRIM() or STRTOUPPER(), and stuff like that) operate on all the
variables passed by POST from a range of web forms without writing
these actions specifically for each form's variables?
The number, and names, of the variables passed by POST wil vary with
each form.
I suppose I'm looking for a script which I can make as an include()
which I can call to do the business, irrespective of the names and
numbers of the variables passed.
Rather than re-inventing the wheel, does anyone know if there is an
existing script which will do that?
TIA.

yup, treat $_POST as you would an array because it is an array

example
foreach($_POST as $key => $item)
{
$$key = trim($_POST[$key]);
}

key is a variable variable

it would be the equivalent of this

$apple = $_POST['apple'];
$orange = $_POST['orange'];
$pear = $_POST['pear'];

etc..

with the loop above you don't have to go thru the process of calling each one out
it's done throu the loop - hope that makes sense

Thank you. I've never worked with foreach (Shock! Horror!) so it'll
be interesting to see how I get along with it.
