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??

Something like this maybe?

<? //untested
foreach($array as $key=>$value){
  if(!isset($array[$key])){
    $errorflag = 1;
  }
}
?>

That doesn't work.  Only the last value is assigned;

if all you want to know is whether any one is empty, then

$err_msg= '';

foreach($array as $key=>$value){
 if(empty($value)){
        $err_msg= "$key is empty";
        break;
}

echo $err_msg;

Or
$err_msg= '';

foreach($array as $key=>$value){
 if(empty($value)){
        $err_msg .= "$key is empty<br>";
}

echo $err_msg;
