| The reason I want to do what I want to do is two-fold:
|
| 1. Preserve entered data in the fields in case the form is not properly
| filled out.

which setting posted variables to null accomplished...in reverse. ;^)

| 2. Use an array structure for error checking and changing the CSS
| properties to visually indicate an error on the page.

which has nothing to do with setting the $_POST *array* values to null.

| --Like I said, I've done this before, I'm just looking for a short form
way

function senselessButAskedFor(&$value)
{
$value = null;
}

array_walk('senselessButAskedFor', $_POST);

short enough?
