I have rows of input fields
Each row contains 3 fields.  The user must fill out
the entire row (all 3 fields) for things to work
right. 

I want to generate an error in case they have only
filled in 1 or 2 of the boxes.
Thinking I might use something like this:
foreach($skills as $key => $skill)
    {
    if ($skill != '' && $skys[$key] = '' &&
$slus[$key] = '')
    {
        }else if{
    if ($skill = '' && $skys[$key] != '' &&
$slus[$key] = '')
BEWARE -  single equal sign assigns right operand to the left one, you 
need doulble, which compares and returns either false or true.

    }else{
    if ($skill = '' && $skys[$key] = '' && $slus[$key]
!= '')
..... above only takes into account that 1 of that 3
has been filled in.  I would need another set to take
into account if 2 of the 3 have been filled in.
Is there a simpler way / shorter way to check
conditions to do this ?
foreach($skills as $key => $skill) {
  $filled_in = 0;
  if($skill != '') $filled_in++;
  if($skys[$key] != '') $filled_in++;
  if($slus[$key] != '') $filled_in++;
   if($filled_in < 2) ERROR();
}
