Dynamic Array Index using Variable

[Chris Lott <chris.lott@xxxxxxxxx>]

I want to do something like this to check if a variety of submitted
form fields (crn, instructor, etc) have any value in them:

$reqfields = array('crn', 'instructor');
$errorflag = 0;

foreach ($reqfields as $field) {
	if ($_REQUEST[$field] == '') {
		$errorflag = 1;
	}
}

But I can't quite get the syntax right... help??
